Huge thanks David - when turning of the derivates it now also works on my own data.

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: Error when using iterative coding
Hi David/Stephane,
Sorry for the long delay in response. Unfortunately, your suggestion is not solving the issue. I have tried the loop code on a number of other data sets but still get the same error message. I have then tried it at one of your provided example data and still it doesn't work for ...

Re: Error when using iterative coding
Hi Stephane,
Sorry, that's a leftover from testing whether the problem was related to first 40 alternatives. It should naturally be set to 1. It does, however, not influence the error message, which still says that b_distance is not influencing the log-likelihood.
Cheers

Error when using iterative coding
Hi,
I have RP data with a large number of alternatives. I have therefore used the interative coding which is mentioned in the manual, chapter 11. Unfortunately, I get an error which I cannot resolve and therefore I ask the forum for help.
My iterative code looks like this (for simplicity I here ...
