ApolloChoiceModelling forum

We are trying to estimate an MNL model for location choice. We have 200 zones as alternatives. For utility equation we are using the following code:

for(j in 1:200){
V[[paste0("alt",j)]] = (
b_access*get(paste0("zone_access",j))}

We are getting an error that b_access does not influence the likelihood.
The code runs fine on a MAC OS, but we are using windows (for higher computing power since we have many more variables) and it does not work.
On windows computer, we are using apollo version 0.2.4
Could you please guide us how to specify our utility equations correctly.

can you please show us the entire code and also the full output prior to the failure?

Thank you for your reply. We found out that it was a problem of apollo version. We used an earlier version of apollo and the problem was solved. Thank you!
