ApolloChoiceModelling forum

Hi Stephane,

I am trying to specify a latent class model. But the class is not fixed for each individual over time. In other words, starting from one period, an individual's situation is changed, his status/group is changed. In model specification, I want to include not only individual demographic variables, but also time specific variablbes to indicate that class changes. Is that possible in Apollo?

Thanks,
Sheldon

Hi, sure, this is possible. What you need to do is to only have the call to apollo_panelProd after the averaging across classes, i.e. apollo_lc. So essentially, this is an intra-individual version of LC. The call to apollo_panelProd at the end will mean that you still recognise the repeated choice nature of the data when calculating the standard errors

just so say that there is a small bug preventing this from working at the moment. It's being fixed for version 0.2.8, the development version of which will be on our website in the coming days
