Witold Orlik

Hello,

I think it would be useful if you explained what LGM, LPA, LCGA, and GMM mean. I assume people from your research area know it already, but other researchers could help knowing these details.

Regards, Witold

Berhanu Nigussie Worku

Yes, I absolutely share Witold's idea. Then, people can contribute inputs to the question!

Sorry, means of these words:

LGM——latent growth curve model

LPA——latent profile analysis

LCGA——latent class growth analysis

GMM——growth mixture model
