  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

Ask questions about model specifications. Ideally include a mathematical explanation of your proposed model.

ICLV

Post by Rugg92 »

Dear Apollo users,

I am new to Apollo and I am trying to set up an ICLV model. My model is fairly simple, one dependent binary variable (buy insurance not buy insurance) and around 5 independent latent variable, each of them with 3 or more indicator variables. The latent variables are latent construct that explain the decision of the subject. This is kind similar to the UTAUT framework.

I am having trouble in setting up the model, in particular in specifying the utility and the parameters to be estimated.

Any help?

Hi

it's difficult to offer general help without specific questions or issues. Did you look at the ICLV examples on the website?

Best wishes

Stephane

The main doubt I have is that it seems that i need to specify an utility function, however if subject's choice is no, how should I specify the utility?

Hi

when the outcome is just a yes/no answer, and the attributes are situation rather than alternative specific, then you just make the utility 0 for one of the two alternatives, and put the attributes in the other utility. Only differences in utility matter

Hope that helps
