Hi Stephane, it turns out to be a typo in the coefficient name. It's resolved. A clearer error message could be helpful for new R users like me.
Many thanks!

- 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.

error in testing likelihood function
Hi all, I'm trying to run a conditional logit model on my own panel dataset. Attached is the error that I run in after validation. The code is adapted from example 15, the changes are minor, including the dataset and the variable names etc. Your help is appreciated. Thank you. model = apollo_estimat...

Re: Input validation code works on other PC, not mine
Another thing for us who switch from Stata, importing an dta file will result in "Error in rle(id) : 'x' must be a vector of an atomic type". Try xlsx instead.

GMNL model
Hello all, I'm new to this. Is there a working example of GMNL with Apollo? Would Apollo outperform the r_gmnl package in terms of estimation speed?
Thanks.
Thanks.
