Hello,
I am working on a latent class growth analysis with complex survey weights. There is a discrepancy in the final class counts for the latent classes based on their most likely latent class membership between the numbers presented in the report and when I output the data into a text file and then count the data using STATA. However, there is no difference in the proportion. Please see below for the relevant output in STATA and MPLUS.
MPLUS Output:
Class Counts and Proportions
Latent
Classes
1 2204 0.17842
2 4162 0.33695
3 1534 0.12423
4 4451 0.36040
STATA Output:
----------------------------------------------------------
Class | percentage lb ub obs
----------+-----------------------------------------------
Presiste | 17.84 16.24 19.56 2557
Low-Unhe | 33.7 32.6 34.81 4421

High-Unh | 36.04 34.73 37.37 4065

| The Mplus output is weighted by the survey weights. If a person is classified to be in class 1, we count that person not as 1 but as the standardized sampling weight. The final number is rounded to an integer. If that doesn't resolve the issue, send your example to support@statmodel.com |

| Thank you for that clarification. |
