I am trying to find the best way to run an LGM with 2000 observations. For simplicity, I'll describe only one aspect of the data that I am attempting to model.

Subjects received 2000 Stroop trials and I want to see if reaction time changes across observations.

To make the data fit in Mplus, I first thought of taking the average RT across a set but I lose a lot of information when I go that route.

Does anyone have any suggestions?

Thank you!

I think you are saying that you have 2000 time points and want to study change over those time points. The handout and video on or website from the Utrecht Version 7 training in August 2012 discusses approaches for these type of longitudinal data.

Thanks for your response! I found the handouts but I couldn't find the videos that you're talking about. Could you please post a link?
