Hi Stephane,
Thanks a lot. I overlook this Apollo_example_3.r.
Wishing you a Merry Christmas along with a Happy New Year!

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.

Direct choice elasticity and cross elasticity of parameter estimates of models using different decision rules
Hi all, In order to compare coefficient parameters in models using different decision rules, namely random regret minimization and random utility maximization, Hensher, Greene and Chorus (2013) and Chorus and Bierlaire (2013) put forth using the direct choice elasticity and cross elasticity of param...

Error message "duplicated componentName" in Hybrid Choice Model using Bayesian approach
When I run the example "hybrid_model_bayesian.r" in this website using Apollo v 0.2.1, the following error message appears: Apollo found a model component of type OL without a componentName. The name was set to "OL" by default. Error in apollo_ol(ol_settings2, functionality) : Du...

Online course in choice modelling and stated choice survey design?
While the subject is not relevant to the software feature, as there is no other suitable topic in the forum, please allow me to state the request here. I am interested in the course on choice modelling and stated choice survey design as well as the Advanced choice modelling course offered by CPD. Gi...
