Mongolian Multivariate Statistics (at the Mongolian University of Life Sciences)
I was delighted to be invited to return to Mongolia again for a more indepth visit to the Mongolian University of Life Sciences [Хөдөө Аж Ахуйн Их Сургууль]. I was honored by the invitation from the Dean of the School of Economics and Business [Эдийн засаг бизнесийн сургууль], B. Baasansukh, and P. Munkhtuya, Chair of the Department of Economic Statistics and Mathematical Modeling, to come and teach a one week Short Course on Applied Multivariate Statistical Methods with R [Олон хэмжээст статистикийн богино хэмжээний сургалт R программ дээр]. This post is a brief summary of my trip.
I got to Ulaanbaatar on my first ever flight on MIAT Mongolian Airlines, which was quite comfortable.
On Monday, February 26, we jumped right into work. The material for the short course was adapted from the book and associated R code by Brian Everitt and Torsten Hothorn, An Introduction to Applied Multivariate Statistical Analysis with R, Springer, 2011. The eight chapters of the book were covered in four days. Topics covered were the following:
 R environment, setup, basics
 Multivariate Analysis – what is it?
 Data Exploration and Visualization
 Principal Components
 Multidimensional Scaling
 Exploratory Factor Analysis
 Confirmatory Factor Analysis
 Structural Equation Modeling
 Cluster Analysis
 Repeated Measures
The Everitt and Hothorn text was particularly useful for its compact treatment of complex topics, and the selfcontained nature of the included R code demo modules.
There were a total of 31 participants attending, although course and meeting conflicts prevented some from coming every day. The MULS School of Economics and Business had 20 participants, with the remaining attendees coming from the Division of Science and Research, the School of Agroecology, the School of Veterinary Medicine, and the School of Engineering and Technology. Outside of MULS, participants also came from the National Statistics Office of Mongolia and the Cabinet Secretariat of the Government of Mongolia.
All participants followed along by executing sample code on their own laptops. All presentation materials and code are available from https://github.com/ryandata/multivariate. Supplemental texts and files were made available using a portable PirateBox to distribute materials via local wireless network. See this post on how to set up a PirateBox.
The interaction was lively and particularly aided by assistance in translation from G. Bilguun, O. Amartuvshin, and T. Suvdmaa. I hope the participants enjoyed it as much as I did!
Putting our knowledge of R to immediate use, we used R to select a random sample of winners of swag provided by Rutgers’ Master of Business and Science program.
During the week, I also had the opportunity for several meetings to discuss future collaborations on projects to improve the academic and data infrastructure of MULS, which I believe will be the subject of future collaborations. The week also included some delicious food, including a hot pot dinner and khorkhog [хopxoг] and khuushuur [хуушууp].
On Thursday afternoon, I had the opportunity to address a group of undergraduate statistics majors on trends in data science and its intersection with statistics. I argued that the expansion in the power and availability of open source software and data has made it possible for anyone, from Mongolia or even the United States (where there are arguably more distractions) to study and master the tools and skills that underpin the most dynamic growth sectors for future jobs.
Finally on Friday, we wrapped up the course with some final discussion and the presentation of certificates to participants.
Mongolia is always a land of warm welcome and surprises. Thanks to my hosts at SEBMULS for a fantastic trip, filled with learning. Thanks to D Music for inspiration as always. And thanks especially to P. Munkhtuya for leading all of the organizational efforts for my visit. I am looking forward to working together with MULS colleagues in the future! Маш их баярлалаа!
Statistical Software and Data Workshops, Spring 2018
New Brunswick Libraries Data Workshop Series
Spring 2018
This Spring, Ryan Womack, Data Librarian, will repeat the series of workshops on statistical software and data visualization as part of New Brunswick Libraries Data Management Services. A detailed calendar and descriptions of each workshop are below. The workshop on reproducible research is moving online to YouTube – stay tuned for an upcoming blog post and announcement on its availability.
This semester each workshop topic will be repeated twice, once at the Library of Science and Medicine on Busch Campus, and once at Alexander Library on College Ave. These sessions will be identical except for location. Sessions will run approximately 3 hours. Workshops in parts will divide the time in thirds. For example, the first SPSS, Stata, and SAS workshop (running from 123 pm) would start with SPSS at 12 pm, Stata at 1 pm, and SAS at 2 pm. You are free to come only to those segments that interest you. There is no need to register, just come!
Logistics
Location: The Library of Science and Medicine (LSM on Busch) workshops will be held in the Conference Room on the 1st floor of LSM on Mondays from 12 to 3 pm. The Alexander Library (College Ave) workshops will be held in room 413 of the Scholarly Communication Center (4th floor of Alexander Library) from on Tuesdays from 1:10 to 4:10 pm.
For both locations, you are encouraged to bring your own laptop to work in your native environment. Alternatively, at Alexander Library, you can use a library desktop computer instead of your own laptop. At LSM, we will have laptops available to borrow for the session if you don’t bring your own. Room capacity is 25 in both locations, first come, first served.
If you can’t make the workshops, or would like a preview or refresher, screencast versions of many of the presentations are already available at http://libguides.rutgers.edu/data and https://youtube.com/librarianwomack.

§ Introduction to R (February 5 or February 6) – This session provides a threepart orientation to the R programming environment. R is freely available, open source statistical software that has been widely adopted in the research community. Due to its open nature, thousands of additional packages have been created by contributors to implement the latest statistical techniques, making R a very powerful tool. No prior knowledge is assumed. The three parts cover:
 Statistical Techniques: getting around in R, descriptive statistics, regression, significance tests, working with packages
 Graphics: comparison of graphing techniques in base R, lattice, and ggplot2 packages
 Data Manipulation: data import and transformation, additional methods for working with large data sets, also dplyr and other packages from the tidyverse useful for manipulation.
Additional R resources, including handouts, scripts, and screencast versions of the workshops, can be found here: http://libguides.rutgers.edu/data_R
R is freely downloadable from http://rproject.org
§ Data Visualization in R (February 12 or February 13) discusses principles for effective data visualization, and demonstrates techniques for implementing these using R. Some prior familiarity with R is assumed (packages, structure, syntax), but the presentation can be followed without this background. The three parts are:
 Principles & Use in lattice and ggplot2: discusses classic principles of data visualization (Tufte, Cleveland) and illustrates them with the use of the lattice and ggplot2 packages. Some of the material here overlaps with Intro to R, pt 2, but at a higher level.
 Miscellany of Methods: illustrates a wide range of specific graphics for different contexts

Mongolia GIS
While researching my upcoming Mongolia trip, I was amazed to discover a treasure trove of Mongolian data already at Rutgers. Christopher Free, a quantitative ecologist, studies Mongolian fisheries, and is an R and GIS expert to boot. He has compiled a onestop archive for Mongolian GIS data and R courses that use Mongolian fish data as examples [much better than sports statistics!].
These are exactly the kinds of global connections I am delighted to make!
Survival Analysis in R video available
As promised earlier, the “special topic” material on Survival Analysis is now available on YouTube in lieu of inperson sessions. Take a look at the Survival Analysis in R Playlist.
Survival analysis deals with data that may have truncated observations, called censored data. A typical example is studying the time until failure of a part in engineering, or failure of a part of the human body in medicine (colloquially known as “disease”). We usually have some accurate data on when the problem occurs until the point that the end of the study is reached. Then we will have some subjects that survived without failure until the end of the study, but we are uncertain just how long they would have lasted until failure. The methods of survival analysis account for this partial uncertainty in the data. R can deal with almost all necessary aspects of survival analysis, but requires some mixing and matching of packages to get the best results, as shown in the videos.
As always, my YouTube videos are fueled by music behind the scenes. Giving a throwback shoutout to Public Image Limited, some holiday Twice, plus the usual Mongolian suspects.

 Best Practices for Managing Your Data – methods to organize, describe, backup, and archive your research data in order to ensure its future usability and accessibility. Developing good habits for handling your data from the start will save time and frustration later, and increase the ultimate impact of your research.
 Data Management Plans, Data Sharing and Archiving – targeted to researchers who need to write data management plans (DMPs) and share their data as part of their grant application, research and publication process. Reviews DMP guidelines, checklist, and general advice, along with options for sharing and permanently archiving research data.
 Reproducible Research – covers the growing movement to make the products of research accessible and usable by others in order to verify, replicate, and extend research findings.

Data Visualization and R
Well, it has been a long time in coming, but I have finally finished converting my Data Visualization workshop series to a screencast video version. See this YouTube playlist for the complete series, and the materials at Github. This is the long version of the inperson 3 hour workshop. The video series goes into even more detail, starting from a history of major developments in visualization, to various implementations of specific graphs, interactive visualizations, web viz, big data, and more.
I also have some ideas for some more uptodate addins that I will probably record as lagniappe videos over the next few weeks. Those didn’t quite fit into the existing sequence of videos.
The energy to complete these videos came from several musical sources, of which I would credit Harmogu and Linton Kwesi Johnson as leading lights.

§ Introduction to R (February 1 or February 2) – This session provides a threepart orientation to the R programming environment. R is freely available, open source statistical software that has been widely adopted in the research community. Due to its open nature, thousands of additional packages have been created by contributors to implement the latest statistical techniques, making R a very powerful tool. No prior knowledge is assumed. The three parts cover:
 Statistical Techniques: getting around in R, descriptive statistics, regression, significance tests, working with packages
 Graphics: comparison of graphing techniques in base R, lattice, and ggplot2 packages
 Data Manipulation: data import and transformation, additional methods for working with large data sets
Additional R resources, including handouts, scripts, and screencast versions of the workshops, can be found here: http://libguides.rutgers.edu/data_R
R is freely downloadable from http://rproject.org
§ Data Visualization in R (February 8 or February 9) discusses principles for effective data visualization, and demonstrates techniques for implementing these using R. Some prior familiarity with R is assumed (packages, structure, syntax), but the presentation can be followed without this background. The three parts are:
 Principles & Use in lattice and ggplot2: discusses classic principles of data visualization (Tufte, Cleveland) and illustrates them with the use of the lattice and ggplot2 packages. Some of the material here overlaps with Intro to R, pt 2, but at a higher level.
 Miscellany of Methods: illustrates a wide range of specific graphics for different contexts
 3D, Interactive and Big Data: presentation of 3D data, interactive exploration data, and techniques for large datasets
Additional R resources can be found here: http://libguides.rutgers.edu/data_R
R is freely downloadable from http://rproject.org
§ Special Topics (February 15 or February 16) covers a few different specialized areas. The three parts presented during the afternoon workshop are not related.
 Time Series in R: review of commands and techniques for basic time series analysis in R. Scripts at http://libguides.rutgers.edu/data_R
 Survival Analysis in R: review of commands and techniques for basic survival analysis in R. Scripts at http://libguides.rutgers.edu/data_R
 Big Data in Brief: an introduction to some of the techniques and software environments used to work with big data, with pointers to resources for further learning at http://libguides.rutgers.edu/bigdata
Of related interest: There is also a Digital Humanities Workshop Series this spring, covering topics including text analysis, network analysis, and digital mapping. See https://dh.rutgers.edu/spring2016workshops/ for information on the topics and schedule.
Data Workshops Full, Registration Closed
Somehow the response this Fall was much higher than expected, so all data and statistical software workshop sessions are now full and registration is closed. Please consult the screencasts, scripts, and handouts at libguides.rutgers.edu/data for a selfguided version of the same material.
The same sessions will run again live in the Spring.
Statistical Software and Data Workshops – Fall 2015
Rutgers University Libraries Data Services Workshop Series (New Brunswick)
August 2015
This Fall, Ryan Womack, Data Librarian, will give a series of workshops on statistical software, data visualization, and data management, as part of the Rutgers University Libraries Data Services. To go directly to the registration page, click here. A detailed calendar and descriptions of each workshop are below. This semester each workshop topic will be repeated twice, once at Alexander Library on College Ave, and once at the Library of Science and Medicine on Busch. These sessions will be identical except for location. Sessions will run approximately 3 hours. Workshops in parts will divide the time in thirds. For example, the SPSS, Stata, and SAS workshop would start with SPSS at 1:10, Stata at 2:10, and SAS at 3:10. You are free to come only to those segments that interest you.
Logistics
Location: The Alexander Library (College Ave) workshops will be held in room 415 of the Scholarly Communication Center (4th floor of Alexander Library) from on Wednesdays from 1:10 to 4:10 pm. The Library of Science and Medicine (LSM on Busch) workshops will be held in the Conference Room on the 1st floor of LSM on Thursdays from 12 to 3 pm. Pay attention to the different locations and times when signing up.
For both locations, you are encouraged to bring your own laptop to work in your native environment. Alternatively, at Alexander Library, you can use a library desktop computer instead of your own laptop. At LSM, we will have laptops available to borrow for the session if you don’t bring your own. Room capacity is 25 in both locations.
If you can’t make the workshops, or would like a preview or refresher, screencast versions of many of the presentations are already available at http://libguides.rutgers.edu/data. Additional screencasts are continually being added to this series.
