Hi Stata users,I am running a Gompertz survival model with no time varyingvariables. I am looking at mortality within states and I includeindicator variables for each state. In one model, I accidentlyincluded both the state indicator variable AND a state levelvariable. In the OLS world that would be a case for perfectcollinearity and the coefficient on the state-level variable wouldnot have been estimated, but in this case it was! My gut tells methat the estimates are wrong/uninterruptable statistical garbage...Am I right ?Please an help would be great!
