Create an equation object with the underlying fixed-effects estimation of a difference-in-difference equation.
For panel equations estimated using the difference-in-difference method.
Syntax
eq_name.didmakeeq new_eqname
You should follow the didmakeeq keyword with the name of the new estimated equation with an equivalent specification to be created in the workfile.
Example
equation eq1.did asmrs @ post
eq1.didmakeeq eq_underlying
estimates an equation by difference-in-difference with ASMRS as the outcome variable, and POST as the treatment variable, and then creates the underlying fixed effects estimation in the equation object EQ_UNDERLYING
