After an estimation with fixed effects, my e(b) matrix dmension change from a computer to another
After an estimation with fixed effects, my e(b) matrix dmension change from a computer to another

Hi,

After an estimation with fixed effect (with OLS or PPML) such as "ppml v dist contig tariff FE_it* FE_jt*", we noticed with my supervisor that the matrix of coefficient e(b) didn't have the same dimension when I executed the code on my computer or when she did it. In her case, coefficient corresponding to omitted FE are present in the matrix and equal to zero. In my case, these coefficient don't appear in the matrix. Therefore, our matrices e(b) don't have the same size, and it's problematic for what I want to do next.

We have exactly the same version of STATA (15.1). Would you know where can the difference come from ? Maybe parameters ? And how to switch from one situation to another ?

Thanks a lot, hope it's clear enough.

Lucile
