Important: Read this before posting to this forum
- This forum is for questions related to the use of Apollo. We will answer some general choice modelling questions too, where appropriate, and time permitting. We cannot answer questions about how to estimate choice models with other software packages.
- There is a very detailed manual for Apollo available at http://www.ApolloChoiceModelling.com/manual.html. This contains detailed descriptions of the various Apollo functions, and numerous examples are available at http://www.ApolloChoiceModelling.com/examples.html. In addition, help files are available for all functions, using e.g. ?apollo_mnl
- Before asking a question on the forum, users are kindly requested to follow these steps:
- Check that the same issue has not already been addressed in the forum - there is a search tool.
- Ensure that the correct syntax has been used. For any function, detailed instructions are available directly in Apollo, e.g. by using ?apollo_mnl for apollo_mnl
- Check the frequently asked questions section on the Apollo website, which discusses some common issues/failures. Please see http://www.apollochoicemodelling.com/faq.html
- Make sure that R is using the latest official release of Apollo.
- Users can check which version they are running by entering packageVersion("apollo").
- Then check what is the latest full release (not development version) at http://www.ApolloChoiceModelling.com/code.html.
- To update to the latest official version, just enter install.packages("apollo"). To update to a development version, download the appropriate binary file from http://www.ApolloChoiceModelling.com/code.html, and install the package from file
- If the above steps do not resolve the issue, then users should follow these steps when posting a question:
- provide full details on the issue, including the entire code and output, including any error messages
- posts will not immediately appear on the forum, but will be checked by a moderator first. We check the forum at least twice a week. It may thus take a couple of days for your post to appear and before we reply. There is no need to submit the post multiple times.

Re: Reporting results of CFA in HCM
Dear Stephane
For simultaneously estimated HCM, do the latent variables need to meet CFA criteria (e.g., CR, AVE)? What methods can be used to demonstrate the construct reliability of latent variables?
Thanks a lot!

Re: panel data for latent class model
Dear Stephane,
Thank you very much for you response!
My model is hybrid latent class, also class-specific error components are included in the choice model. The error component estimation results indicate that, one class is insignificant, one class is siginificant positive, one class is siginificant ...

Re: panel data for latent class model
Dear Stephane,
Does this case require creating an error component for each alternative, and then multiplying the class-specific but alternative-unspecific coefficients by the alternative-specific error components and adding them to the corresponding utility functions? I've seen articles with class ...
