ApolloChoiceModelling forum

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

Stephane
