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. This may take a day or two at busy times. There is no need to submit the post multiple times.

Yes, that does it. Thanks a ton, David!

Hi-I am getting a similar error with the code below, however I do not see where the mistake is (even after consulting this thread). Thanks a lot for your help! # ################################################################# # #### LOAD LIBRARY AND DEFINE CORE SETTINGS #### # ####################...

Re: Error in Bayesian estimation
Indeed, thanks so much-I just added:
nodiagnostics=TRUE.
nodiagnostics=TRUE.

Error in colMeans(model$F) when attempting HB estimation
Dear Stephane, Trust you are well and many, many thanks for having made Apollo available, as well as this forum. I am trying to estimate a latent class model with continues random parameters using Bayesian estimation. Whilst the diagnostic test is passed, Diagnostic checks passed. Please review befo...
