mx_lca: Estimate latent class analyses using OpenMx

Description

This function simplifies the specification of latent class models: models that estimate membership of a categorical latent variable based on binary or ordinal indicators.

Usage

mx_lca(data = NULL, classes = 1L, run = TRUE, ...)

Value

Returns an OpenMx::mxModel().

Arguments

data

The data.frame to be used for model fitting.

classes

A vector of integers, indicating which class solutions to generate. Defaults to 1L. E.g., classes = 1:6,

run

Logical, whether or not to run the model. If run = TRUE, the function calls OpenMx::mxTryHardOrdinal().

...

Additional arguments, passed to functions.
