Hi everyone, I have a question regarding conditional logit model. I have a model examining the location choice of new firm for 4 years, which means each firm only appears in one year.
1. When I run the conditional logit model, do I need to account for this time dimension or just run the model like conditional logit model (CLM) for cross section.
2. X1...X4 are individual specific while Z1...Z6 are provincial specific. Would you mind checking my codes? The model does not seem to converge. Iterations keep saying "not concave".
3. With my data set as below, do I need other codes to set up the data before running (CLM) or just run the above code to get the result?
4. In my real data set, technology level also receives value "2". What are the codes for running two separate regressions for firms with techonology = 1 and firms with technology = 2.
Really look forward to your help. Thank you so much!

Code:
asclogit province_chosen Z1 Z2 Z3 Z4 Z5 Z6, case(id) alternatives(province) casevars (X1 X2 X3 X4)
4. In my real data set, technology level also receives value "2". What are the codes for running two separate regressions for firms with techonology = 1 and firms with technology = 2.
Really look forward to your help. Thank you so much!
