Latent profile analysis with complex survey data

[coby18]

Hi! I want to figure out how to perform a latent profile analysis on a component of the CDC's BRFSS (a complex survey database) for my honors thesis at Stanford. I know this analysis can be done with m plus, but apparently that software is pretty expensive and not very user-friendly. Does anyone know how to perform a latent profile analysis on complex survey data using any other type of software (including SAS, Stata, or R?) Any help would be greatly appreciated!!
