Hi all,

I have data from a discrete choice experiment in which respondents were shown 12 choice tasks. For each choice task, they were asked if they would like to make a purchase, and if so, which of two alternatives they would prefer. Each alternative was characterized by a set of attributes. The choice tasks included alternatives with different variations of levels of these attributes (but the same set of attributes).

I would like to run a nested logit model, in which the upper level is a decision to purchase or not, and the lower level is which alternative (if they are purchasing either). I'm having some trouble finding examples of using nested logit with multiple responses per individual (ie panel data). Is it appropriate to be using this approach and is it possible to use nlogit here?

Much appreciated.

Thank you,
Seema Kacker
