I made a Nested logit model. Level 1: 8 choices and level 2: 22 choices.
In type 4, I have only 1 choice in level 1 corresponds to one choice in level 2.
The dissimilarity parameters are equal to 1 in this case (not surprising).
Can i run the model normally when i have a an IV parameter than is equal to one?
The results can be interpreted normally or what should i have to do in this case?
I tried the commande "constraint 1=[type4_tau]_cons=1" but the model does not run.
what can i do?
Thanks in advance for your advices
II would take the variables of Half the sample and factor analyze. Look at the factors If they seem to be stable and I would useThem And use them as predictor variables.I would then double cross validate them .and see how they predict. This would give me on the estimate stability. Which is more important in this case then significance I have suggested this a number of times and previous research and it has been found to be insightful and useful.
