Goodness of fit for CBC HB

By Robin Alikhani | Aug 05, 2017 08:35PM CEST

Hi

How can I interpret the result of goodness of fit for choice based conjoint hierarchical baye. This includes observations, Sum of weights, likelihood, rlh.

Best regards
Robin

Hi Robin,

Thanks for your message.
For each of the (n) individual you have (k) choices within each of the (m) comparisons.
The observations are equal to n x k x m.
The sum of weights corresponds to a weighted number of observations – this depends on whether you filled the response weights in the dialog box.

The likelihood does not have a straightforward interpretation, but the root likelihood (rlh) does have one: it is bound between 0 and 1. The higher the rlh, the better the fit.

Jean Paul
