Hi: I am running a LCA model based on 9 ordinal variables. The model results showed that my chi-square values differ significantly in Pearson and LR chi-square. Given the df is the same, therefore, the significant test is varied (Pearson chi-square test is significant but LR test is insignificant). I am wondering which test I should trust and how can I fix this problem? Thank you so much!

When they do not agree, neither should be used.

Thank you Dr. Muthen. Is that meaning my model is not trustworthy given these two tests disagree each other? How could I fix it, or is that I simply report other index (e.g., entropy, AIC, BIC)? Thanks!

It is more a shortcoming of the tests. Report another index.
