CLCM - Confirmatory Latent Class Models

CLCM, an R package for estimating confirmatory latent class models with clinical data types.

Description

Estimate confirmatory latent class models for a variety of item response types that are encountered in the clinical field. Latent regression estimation can be performed, allowing for comparisons of longitudinal latent class assignments (e.g., treatment success/failure) across observed groups (e.g., treatment arms in clinical trials). Fit statistics (C2, AIC/BIC) are available as well.

Installation

You can install the released version of CLCM from github:

install.packages('devtools')
library(devtools)
devtools::install_github("CJangelo/CLCM")

The goal is to release this package on CRAN - I am looking for volunteers to help me with testing required to support a CRAN submission.

Examples

For concise examples of how these models can be applied to clinical data, see the Vignettes under Articles at the top of this page.
