Dear Statalisters,

I have two related questions: (1) how does STATA tranform dummy variables, which change over time, in a fixed effects regression and (2) can I interpret the coefficient estimates for these dummy variables in a typical fashion i.e., wrt the omitted dummy or does the transformed variable require a different interpretation of the coefficient estimate.

A simplified version of the county-level fixed effects regression I am running is as follows:

xtreg y d1 d2 d3 X t, fe

where:
y is a continuous variable
d1..d3 represent time varying dummy variables with the omitted dummy being (d4).
X represents a vector of time varying continuous explanatory variables.
t represents a vector of time dummy variables.

Id greatly appreciate your thoughts.

Sincerely,
