Important: Read this before posting to this forum

  1. 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.
  2. 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
  3. Before asking a question on the forum, users are kindly requested to follow these steps:
    1. Check that the same issue has not already been addressed in the forum - there is a search tool.
    2. 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
    3. Check the frequently asked questions section on the Apollo website, which discusses some common issues/failures. Please see http://www.apollochoicemodelling.com/faq.html
    4. Make sure that R is using the latest official release of Apollo.
  4. If the above steps do not resolve the issue, then users should follow these steps when posting a question:
    1. provide full details on the issue, including the entire code and output, including any error messages
    2. 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.

Hi David,

I have emailed the dataset and full R script.

Thank you,

Re: WTP Space Mixed Logit with piecewise price parameter

Dear Stephane, Thank you. I m trying to implement a zero censored normal for some the attributes as a fairly large minority of respondents would be expected to be indifferent to them. I used the pmax() function in the randcoeff specification however I get the following warning when running apollo_es...

Re: WTP Space Mixed Logit with piecewise price parameter

Dear Stephane, Thank you for the quick response! I think I will stick to the preference space then and will look into the semi-non-parametric distributions. I am assuming the best way to compute confidence intervals for the mean WTP/WTA would then be to use simulations (Krinsky-Robb method)? Thank y...

WTP Space Mixed Logit with piecewise price parameter

Dear Stephane, Thank you for creating this package and the forum it has been really helpful so far. I am trying to estimate a mixed logit model in the WTP space for a discrete choice experiment. The price attribute is an expected change in bill in percentage points(this can be either positive negati...
