Built on 'multilevLCA' (Lyrvall et al., 2025) <doi:10.1080/00273171.2025.2473935> for Step-1 measurement model estimation, this package extends it with support for Gaussian, Poisson, and binomial distal outcome families. Unlike 'poLCA', which relies on one-step estimation and cannot accommodate a measurement model from a different sample, this package uses a stepwise approach to prevent the structural model from influencing latent class formation. Implements correct sandwich variance estimation that propagates measurement uncertainty from the first-step 'LCA' through classification-error correction in the final step (Bakk, Oberski & Vermunt, 2014). Supports polytomous items and missing data in the measurement model with 'FIML'. A data-generating process replicating the Bakk & Kuha (2018) simulation study is included.https://github.com/r-universe/samleebyu/actions/runs/29185227486Tue, 30 Jun 2026 03:42:55 GMTtseLCA1.0.0successhttps://samleebyu.r-universe.devhttps://github.com/samleebyu/tselcatseLCA-workflow.RmdtseLCA-workflow.htmltseLCA Workflow2026-06-27 03:05:142026-06-30 02:44:47
