Coefficient Sign Comparison estimating xtlogit with fe over two different time periods.

[Gerald Haberer]

Dear all,

I'm analysing my data using xtlogit with fe. Due to a numeric overflow I had to split up my sample into two time periods.
I perform my main analyses with the current time period. In the robustness analyses, I now want to compare the results of estimating the same model over the two different time periods. Can differences in the sign of the coefficients of the two models be interpreted without problems?

Best regards,

Gerald
