CATE and LATE in Stata: Conditional average treatment effects and local average treatment effects

Instructor: Eduardo García Echeverri, Senior Econometrician, Communications

Date: Wednesday, 5 August 2026

Time: 8:30–10:15 a.m. ET

Fee: $60 to $75

In this workshop, we present two of the latest features for causal inference added into Stata 19: conditional average treatment-effects (CATE) and local average treatment-effects (LATE) estimation. We cover the assumptions of both models, discuss when to use which, and demonstrate how to easily implement them with many practical examples using the software. [Read more ...]

Multilevel and mixed models in Stata

Instructor: Kristin MacDonald, Executive Director, Statistical Services

Date: Wednesday, 5 August 2026

Time: 8:30–10:15 a.m. ET

Fee: $60 to $75

This workshop covers the use of Stata to fit multilevel (mixed) models, models that contain multiple levels of nested random effects. These effects may take the form of either random intercepts or random coefficients on regressors. After a brief review of the methodology, the course will demonstrate by example the fitting of such models in Stata. The focus will be primarily on linear (Gaussian) models, but binary, count, ordinal, and categorical responses will also be considered. In addition to models with nested effects, models with crossed effects will also be discussed. Specialized within-group error structures, such as heteroskedastic, autoregressive, and spatial exponential structures, will also be covered. No prior knowledge of Stata is required, but familiarity with multilevel modeling will prove useful. [Read more ...]
