Statistical Packages

• sdid_event, a Stata module to implement event study analysis with sdid.
• Packages from the did_multiplegt family I currently update
  • did_multiplegt_dyn, estimation of event-study Difference-in-Difference (DID) estimators in designs with multiple groups and periods, and with a potentially non-binary treatment that may increase or decrease multiple times.
  • stute_test, a non-parametric test, originally proposed by Stute (1997), that the expectation of a dependent variable Y given an independent variable D is linear in D.
  • yatchew_test, a non-parametric test of linearity originally proposed by Yatchew (1997) and improved by de Chaisemartin & D'Haultfoeuille (2024) to be robust under heteroskedasticity.

Stata Utilities

• ecollapse, extended Stata collapse function with support for string concatenation and union.
• StataPostProduce, a Stata package that translates gr_edit commands into user-friendly codes, a.k.a. the One Piece of Stata Programming.
• runview, a simple plugin to preview Stata help files from VSCode.
• lcollapse, Stata collapse function, but it keeps the labels.

R Utilities

• rnames, recursive display of items in R nested lists.

Lots of other programming shenanigans on my Github page.
