I've read that it is possible to have insignificant attributes in latent class which were significant in the logit analysis, is this correct? In my logit analysis all my attributes were significant, but I am not sure if this is still the case.

Do you have an example of a calculation or can you explain how to calculate whether the attributes are significant in the segments or not?

Many thanks in advance

Do I understand you correctly when I say that an attribute is only insignificant when ALL levels have a t-ratio smaller than 1.96? So if only 1 level out of 3 is smaller than 1.96, the attribute itself is still significant within the model?

And should I also test whether for example a 2group model has a better fit than a 3group model based on significance of the attributes and levels?

I hope to hear from you. Thanks a lot!
