%description
Implements BCH (Bolck-Croon-Hagenaars) <doi:10.1093/pan/mph001> and ML
(Vermunt's maximum likelihood) <doi:10.1093/pan/mpq025> approaches for
three-step estimation of latent class models with covariates and distal
outcomes, following Bakk, Tekle & Vermunt (2013)
<doi:10.1177/0081175012470644>, Bakk, Oberski & Vermunt (2014)
<https://www.jstor.org/stable/24573086>, and Bakk & Kuha (2018)
<doi:10.1007/s11336-017-9592-7>. 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 through classification-error correction in
the final step (Bakk, Oberski & Vermunt, 2014). Supports polytomous items
and missing data in the measurement model with full information maximum
likelihood. A data-generating process replicating the Bakk & Kuha (2018)
simulation study is included.
