We have conducted a latent class analysis with data containing about 1.000 participants. With 6 variables in the model, we got a model with four clusters that we like. However, it has a p value that is exactly 1.000. For example, another model with 3 clusters had p value of .088. My question is, is a p value that is exactly 1.000 a problem?

A p-value for which test?

It is a chi square test Lē for assessing how well the model fits the data.
