Please help me with this problem. I tried snowRMM (Latent Class Analysis) with the Jamovi latest version software (2.2.2 current). I have a dataset consisting of 3129 rows and 18 columns/variables (6 = ordinal, 12 = nominal). When I add all the variables, an error message pops up:

"arguments imply differing number of rows: 3,4,2,5,7"

I know what it means, but how to solve this problem?
Please help.

Hi Ahmed_Hossain

The error might be occured due to the text dataset. Therefore, you have to change text dataset into integer values(from 1 to maximum number) as nominal variable format and run LCA analysis. I also attached sample dataset within poLCA R package. This sample data will help.
