get_honestdid_obj_did2s: get_honestdid_obj_did2s

In kylebutts/did2s: Two-Stage Difference-in-Differences Following Gardner (2021)

get_honestdid_obj_did2s

Description

a helper function that takes a fixest feols object (likely from did2s) that plugs into honest_did. Note this function assumes the event study coefficients are using i() syntax, e.g. i(rel_year). This should also work for a TWFE event-study model estimated by feols.

Usage

get_honestdid_obj_did2s(est, coef_name = "rel_year")

Arguments

est	A fixest object, likely from did2s.
coef_name	Character. The name of the event-study relative-year variable name, from i(rel_year).

Value

A list containing the vector of event-study coefficients beta, the variance-covariance matrix of beta, V, and a vector of relative years, event_time.
