Hello everyone,

I am currently working on Latent Profile Analysis using tidyLPA package. The results show some warning messages, but I do not know the reason. Does anyone know the solution for the warning messages?

## The messages are below.:

Warning messages:

1: In (function (data, modelName = NULL, nboot = 999, level = 0.05, ... :

some model(s) could not be fitted!

2: In (function (data, modelName = NULL, nboot = 999, level = 0.05, ... :

some model(s) could not be fitted!

3: Mclust could not estimate model 2 with 3 classes.

4: Mclust could not estimate model 2 with 4 classes.

5: Mclust could not estimate model 2 with 5 classes.

6: Mclust could not estimate model 2 with 6 classes.

7: Mclust could not estimate model 2 with 7 classes.

8: Mclust could not estimate model 2 with 8 classes.

9: Mclust could not estimate model 6 with 3 classes.

10: Mclust could not estimate model 6 with 4 classes.
