Upcoming Workshops, Spring 2025
Binary Logistic Regression in Stata, Monday, May 12, 2025 from 1 to 4 p.m. PT via Zoom
The analysis of binary outcomes is widespread across scientific fields. This workshop introduces the basics of the most commonly used statistical model for binary outcomes, logistic regression. Some basic background on probability and odds will be provided, as well as a brief review of the model itself. This workshop then covers how to run a logistic regression in Stata, as well as estimating predictions and marginal effects, graphing model predictions, and assessing model fit. A little background in Stata is assumed.

Using the SPSS Mixed Command, Monday, May 19, 2025 from 1 to 4 p.m. PT via Zoom
The purpose of this workshop is to show the use of the mixed command in SPSS. Although it has many uses, the mixed command is most commonly used for running linear mixed effects models (i.e., models that have both fixed and random effects). Such models are often called multilevel models. Because the purpose of this workshop is to show the use of the mixed command, rather than to teach about multilevel models in general, many topics important to multilevel modeling will be mentioned but not discussed in detail. References will be provided so that those interested in these topics can find additional information.

Introduction to Power Simulations in R, Monday, June 2, 2025 from 1 to 4 p.m. PT via Zoom
This workshop introduces power analysis and simulations to assess power and estimate sample sizes needed for sufficient power. We will begin with simple analyses such as the t-test and will work our way up to various regression models. We will provide guidance in R to program simple Monte Carlo simulations to assess power. Some background in programming loops would be helpful but is not necessary.

Introduction to directed acyclic graphs (DAGs) for causal inference in R, Monday, June 9, 2025 from 1 to 4 p.m. PT via Zoom
Directed Acyclic Graphs (DAGs) have emerged as an important tool in causal modeling to understand the relationships among variables. DAGs can inform what variables should be included or excluded in a statistical model intended to minimize bias in the estimation of a causal effect. This workshop discusses the basics of DAGs used for causal inference and outlines simple rules one can follow to know which variables to include in a causal statistical model. The R package daggity will be discussed to visualize DAGs.
