Hi,
I just want to get confirmation if the model fit values I got from CBCHB estimation are just fine. My sample size is 150, I have 5 alternatives per task(including None), 4 attributes with levels 3,2,6,3 respectively. Here are the values I got:
Pct.Cert. - 0.532
RLH - 0.471
Avg. Variance -3.349
Paramter RMS - 1.986
Also, I want to test if interaction effects are significant or including covariates will be significant. Can I say that if my Pct. Cert and RLH increase from those of the main effects only, the model with interaction/covariates is better? To confirm that, will also check the log-likelihood of the 3 models? Thanks in advance!
