DESCRIPTION:Sheps IT Lunch & Learn: Introduction to Difference-in-Differenc
 es\n\nThe Sheps Center is proud to host a Lunch & Learn series this year f
 ocused on statistical methods for analyzing data. These sessions will be f
 acilitated by Chuck Huber from StataCorp. The workshops will be held via z
 oom and registration is required.\n\n \n\nThis talk will briefly introduce
  the concepts and jargon of difference-in-differences (DID) models and sho
 w how to fit the models using Stata’s suite of DID commands. We will dem
 onstrate how to fit models for repeated cross-sectional data using ‘didr
 egress’ and for panel/longitudinal data using ‘xtdidregress’. We wil
 l also fit heterogeneous DID models where the average treatment effect var
 ies over time or cohort using ‘hdidregress’ and ‘xthdidregress’. W
 e will discuss the model assumptions and how to check these assumptions af
 ter fitting a model. We can check the parallel-trends assumption using ‘
 estat trendplots’ and ‘estat ptrends’ and we can check for anticipat
 ion of treatment using ‘estat granger’. After fitting heterogeneous DI
 D models\, we will also demonstrate how to aggregate the average treatment
  effect among the treated (ATET) using ‘estat aggregation’ and how to 
 visualize the trends in ATETs using ‘estat atetplot’.
