I have a 3 class latent class analysis model with categorical observed variables, several categorical covariates and a categorical distal outcome.
When I look at the latent class odds ratios results comparing Class 1 to Class 2, I see that for a couple of my categorical observed variables, the odds ratios are not significant based on the p value. I'm interpreting this as meaning that there are no significant differences in the logits between the two classes for these variables. However, when I look at the 95% confidence intervals for the latent class odds ratio results (using CINTERVAL), the confidence intervals do not cross 1.0, which suggests to me that the difference between the 2 classes is significant.
Can you tell me what might be causing the discrepancy between the p values for the latent class odds ratio results and the corresponding confidence intervals?
