Dear sir or madam,
I am using Apollo to analyze my data by applying a mixed logit model. The MMNL model in my study should deal with both the heterogeneity across individuals and the heterogeneity across repeated choices for the same individual (panel mixed logit model). However, i am a little confused about
how to deal with the panel effects with Apollo, and which parameters should be putted into the "intra--Draws" ? (reference: "Apollo_example_16")
Best regards,
Yue

- 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

- 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

Re: Mixed Logit Model with inter and intra individual heterogeneity
Dear Yue
random components that relate to the individual-level (i.e. what you might call panel effect) should go into inter, those that are at the observation level should go into intra
