title: 'selectTWFE: Model Selection Between TWFE and ETWFE'
version: 0.2.1
abstract: Estimates both a vanilla two-way fixed effects (TWFE) model and an extended
  TWFE (ETWFE) model, then selects between them using Cochran's Q test for heterogeneity.
  When ETWFE wins, reports the heterogeneity fraction (I-squared) and cohort-time
  estimates with empirical Bayes shrinkage and Bonferroni multiplicity correction.
