Am currently trying to conduct an LPA and I am unsure why an error keeps appearing after entering my input.
The output says:
*** WARNING in MODEL command All variables are uncorrelated with all other variables within class. Check that this is what is intended. *** ERROR One or more variables have a variance greater than the maximum allowed of 1000000. Check your data and format statement or rescale the variable(s) using the DEFINE command.
Here are the variances of the variables that mPlus produced in the output:
Continuous Number of Variable Observations Variance
It looks like you use your ID variable among your analysis variables. Either you don't have a USEV list or you have the ID variable on your USEV list.
It sounds like you are using mixture (latent class) modeling. The warning refers to correlations within a class. That doesn't say that your variables are uncorrelated. A latent class variable describes correlations among your observed variables but there is no correlation within class.
