Time-invariant variables in Fixed-effects model - Statalist

WebA fixed effects model can be regarded as a regression with a dummy variable for each group. This dummy variable is time invariant. If you have another variable which is time invariant for a group it is a multiple of the dummy for that group and is thus perfectly colinear with that dummu.
