# Saturday Workshop Series

Since 2010, the CRMDA has offered Software Workshops, often, but not always, on Saturdays. These workshops are typically 3-hours long, and designed to familiarize researchers (including students and faculty) or other interested people with the basics of particular software packages (e.g., Mplus, LISREL, R, Stata, SAS) or methodological procedures (e.g., Multiple Imputation). They take place in Watson Library, Room 455 (unless otherwise noted). Workshops are *free to anyone who would like to attend*. Seminars are run by 1-3 graduate students who are high-end users of the software. Participants are welcome to come simply to learn the basics, or with particular questions in mind.

We encourage you to join our announcement list serve (Methods-L) so you can be informed of events and talks related to methodology. Specifically, Methods-L is an announcement list whereby we periodically inform the KU community about methodology related events (such as the Saturday Seminar Series) or activities that may be of broad interest to researchers at KU. To join the Methods-L list serve please send your name and email address to the CRMDA

**CRMDA Saturday Seminar Schedule 1:00 - 4:00 PM in Watson 455** (unless otherwise noted)

## The Next Workshops Will Be

# LaTeX Workshop

This seminar will demonstrate how to get started using the KU thesis/dissertation LaTeX template through the easy to use (and free!) software LyX.

Topics for this seminar include:

- Introduction to LyX
- How to cheat on your LaTeX Homework Using LyX
- Creating and referencing tables, figures, and equations
- Creating and managing a BibTeX bibliography with JabRef
- Creating and managing separate chapters of your document.

The LaTeX overview by CRMDA is available at latex-help. A university-approved KU Thesis/Dissertation LaTeX template was prepared by CRMDA staff members (see http://www.graduate.ku.edu/formatting). The latest version of that template will always be available within links on latex-help.

We urge participants to set up their personal computers with TeXLive (Linux, Windows) or MacTex (Macintosh) as well as the LyX editor in order to participate fully in the experience. This should be done before the Saturday workshop because the download & installation of the full LaTeX distribution can take several hours.

We know that some users become frustrated with the time it takes to install a LaTeX distribution. For Windows, we have experienced that frustration (with MikTeX, which we previously recommended). During the last semester, we have had good luck with TeXLive (https://www.tug.org/texlive/windows.html). After that is installed, then install LyX (www.lyx.org). Please don't wait until April 8 to try to install & configure LaTeX. It takes more time than you expect. If there is trouble with your computer, please come to CRMDA on Friday, April 7, at 4pm. We can help everybody to understand error messages that result when installing TeXLive or LyX.

For people that don't have personal computers, we have 3 computers that can be checked out. Please let us know in advance if you need to use one of these; we will put your name on a list.

To enroll - send an email to crmda@ku.edu with the subject line of: LaTex - Workshop, Saturday 4/8/17. The enrollment limit will be 20. If the number of enrolled participants is less than 5 on Friday, April 1, 2017, this seminar will be postponed until the Fall.

## Using the KU Thesis and Dissertation template with LaTeX and LyX

Graduate Studies at KU requires each student completing a thesis or dissertation to submit an electronic copy (i.e. (ETD) following a specific format (see http://www.graduate.ku.edu/formatting). Students who use Microsoft Word can find this cumbersome and challenging. Particularly when a document contains many equations, figures, tables, or appendices, the LaTeX document approach may be more likely to result in a uniform, high-quality presentation with correctly numbered tables, figures, and table of contents. LaTeX includes easy tools for cross-references and automatic re-numbering of document elements.

A university-approved KU Thesis/Dissertation LaTeX template was prepared by CRMDA staff members (see http://www.graduate.ku.edu/formatting and a full set of links on http://pj.freefaculty.org/latex).

## Using R for Regression Models and Structural Equation Models

This seminar will extend the knowledge from the Introduction to R seminar. Using an example data set, R syntax will be provided to show you how to: (1) run simple and multiple regressions, (2) check diagnostics for violation of assumptions or influential observations, and (3) visualize results/data for easier interpretation. Ordinary least-squares (OLS) regression will also be compared and contrasted with the Structural Equation Modeling (SEM) framework. Using the same example data, R syntax will be provided to show you how to run the basic special cases of SEM: (1) path analysis, which is a flexible extension of multiple regression; (2) confirmatory factor analysis, which models measurement error in a set of psychological scale items, resulting in a latent theoretical construct free of measurement error; and (3) structural models with regressions among latent variables. The practical advantages of regression (e.g., moderation/interactions, inspecting residuals) and of SEM (e.g., mediation, removing measurement error, handling missing data) will be discussed.

## An Introduction to Programming in Mplus

Mplus is a powerful statistical modeling program that provides researchers from all disciplines with an array of tools for general data analysis. The program draws from a general modeling framework that allows for the evaluation of complex models using both observed and unobserved (i.e., latent) variables. The researcher is offered a wide variety of models, estimators, and algorithms to facilitate use, and Mplus readily accommodates differing variable types, missing data, and complex sampling designs. Furthermore, Mplus features a straight-forward programming language that most researchers find quite approachable.

This seminar provides an introduction to Mplus for beginners while offering experienced users an additional perspective on program use and functionality.

The seminar will have three parts:

- Overview of the Mplus programming language and data importation functions
- Statistical procedures (including but not limited to) multiple regression, exploratory/confirmatory factor analysis (EFA and CFA), structural equation modeling (SEM), and longitudinal modeling (growth curves)
- The seminar will end with a group Q&A session regarding the material and individual project troubleshooting.

Attendees are assumed to have some familiarity with basic statistics including regression analysis. Knowledge of latent variable analysis (structural equation modeling) will enhance understanding but is not required.

## Visualizing and Reporting Regression Results Using Stata

This seminar will provide novice to intermediate Stata users with insights on how to work more effectively, efficiently, and productively through an exploration of Stata's built-in programming language and extensive suite of user-written add-ons.

## Seamless R and C++ integration with Rcpp

The R system for statistical computation and graphics (R Core Team, 2013) has become a pre-eminent platform for data-related research. Its focus on "Programming with Data" has lead to widespread use in data analysis, visualization, statistical computing and general statistical research.

Within the R environment, Rcpp (Eddelbuettel and Francois, 2011; Eddelbuettel 2013) has become the most widely-used language extension. Rcpp permits effortless and seamless bi-directional interchange of objects between the R system and C++ code---covering anything from data containers such as vectors, matrices, and lists to complete (and possibly nested) objects, functions and environments. The ability to seamlessly connect R and C++ enables analysts to obtain substantial speed gains for tasks which are often slow in R (particularly loops, or repeated function calls) with very little effort. It also permits creation of larger-scale projects connecting R to other C++ components or libraries which can take full advantage of the features, and performance, of the C++ language.

This talk will both motivate and introduce Rcpp, and then discuss a key application area. A general overview of Rcpp, suitable to anybody with basic R experience and limited or no C++ knowledge, will be provided in the first half. The second half will then focus on the RcppArmadillo (Francois, Eddelbuettel and Bates, 2013; Eddelbuettel and Sanderson, 2013) integration of the Armadillo library for linear algebra.

## Introduction to Stata

This 3 hour workshop is designed for researchers in the social sciences (although interested researchers from other disciplines are welcome!) with no or little experience with Stata. We will begin with an introduction to the differences between the different flavors of Stata and introduce users to the Stata user interface and syntax, including how to find help and how to search for user-written scripts to extend Stata's capabilities. From here, we will cover the basics of data management in Stata, including importing, merging, and cleaning datasets; recoding variables and generating new variables; and labeling variables and values. We will also provide an overview to Stata's various commands for describing data. Time permitting, we will move on to cover some more advanced topics, including efficient mechanisms for transferring Stata output into Excel, Word, or LaTex, an overview of Stata's graphing capabilities, as well as an introduction to programming in Stata using do-files and some discussion of elementary Stata programming for automation of common or repetitive data manipulation tasks. Along the way, we will provide users with "best practices" learned from years of experience with Stata that will focus on maintaining reproducibility and efficient use of Stata's statistical capabilities. Detailed discussion of any particular statistical techniques (including interpreting Stata output) will not be covered in this course in order to ensure its usefulness to users with differing statistical knowledge and backgrounds.
