Good Day,

I am planning a study that will I analyze using Latent Class Analysis. I have three tests that will be used as inputs to the LCA and I wish to create a 2-class model.

I have some pilot data that I can use and I am looking for resources to calculate the power required for a larger study. Does anyone have any open source /free resources? (e.g. online calculators, R etc)



I don't think this kind of calculator exists so far, but you can automate it a little with LatentGold software, as explained in this Gudicha's paper - it describes how you can calculate power and gives an example code on p.34.

LatentGold is not open source, you can try to reproduce the Gudicha's steps with the other software.
