Bile acids (BAs) have been implicated in obesity-related conditions such as NAFLD and hyperlipidemia. Different human BAs exert variable biological activities. Chen et al. define genetic and microbial associations to plasma and fecal BA concentrations and composition in persons with obesity and establish their relationships with liver fat and lipid phenotypes. The LCA procedure, a user-defined SAS® procedure for conducting LCA and LCA with covariates, is demonstrated using data on substance use from Monitoring the Future, a nationally representative sample of high school seniors who are also followed at selected time points during adulthood.Problems of Drug Dependence 1998: Proceedings of the 60th
The SAS %LCA_Covariates_3Step macro estimates the association between covariates and latent class membership using the approach of Bolck, Croon, and Hagenaars (2004), as adapted by Vermunt (2010) and Vermunt and Magidson (2015). It is a “three-step” (noninclusive) approach, which can be more flexible and robust than the “one-step” approach implemented in PROC LCA’s COVARIATES statement.

Even though a large number of LCA applications include one or more covariates to predict class membership, relatively little is known about how covariates influence estimation quality in LCA. Clark and Muthén (2009) showed that the single-step inclusion method performs best at recovering the true covariate parameter effect, and that it has the ... Mini cooper wiper motor earth.

Keywords: latent class analysis, latent class regression, polytomous, categorical, concomitant. 1. Introduction The aim of this paper is to introduce latent class analysis (LCA) and to demonstrate its applicability in quantitative sociological research. First, we explain the basic concept of LCA and its applications: LCA with a distal variable, multi-group LCA, LCA with covariates, and latent transition analysis (LTA). The purpose of this workshop is to provide social work researchers with an introduction to conducting Latent Class Analysis (LCA) with Mplus. LCA is a statistical modeling procedure used to identify a typology; stated differently, it is used to assess whether subgroups exist within a sample. LCA ca
