When running an LCA with 8 categorical variables and 1492 cases, I keep getting the error:
Categorical variable INJSOM99 contains 127 categories. This exceeds the maximum allowed of 10.
I have looked at the data, and it is coded as 0,1,-99 (with -99 as missing in the mplus input). I have tried to recode the data using SPSS and by hand, in case there was an issue with the zeros being "O"s or something. But, that doesn't seem to fix it. I have also looked if there was missing data in any of the cells, but I don't see any.
You either have blanks in the data set and are reading it in free format causing the data to be misread or the number of variable names in the NAMES statement does not match the number of columns in the data set causing the data to be misread. If you can't see the problem, send the input, data, output, and your license number to email@example.com.

Hello, In terms of interpreting the best solution for a LCA, what do you do if the information criteria fluctuate so there are several "dips" in values? Do you take the first "dip" in the BIC value, even if a second "dip" shows a lower BIC value overall? thanks.
