ApolloChoiceModelling forum

Hi,

Is it possible in apollo to jointly estimate RP-SP data for MDCNEV model? I have successfully used apollo example_22 to do it for a nested logit model with discrete choice but not able to do it for MDCNEV.
The error message: Error in apollo_mdcnev(mdcnev_settings, functionality = "estimate") : object 'j' not found

Thanks in advance.

Hi

there is no a priori why it wouldn't be. But to help us understand why you get the error, you really need to give us more information, including showing the relevant parts of the code

Thanks

Stephane

Hi Stephane,

Thanks for your prompt reply. I was able to solve the issue simply by upgrading apollo version as suggested by one of my colleagues.

Best,
Eeshan
