Description: Implements 'BCH' (Bolck, Croon & Hagenaars, 2004)
        <doi:10.1093/pan/mph001> and 'ML' (Vermunt, 2010)
        <doi:10.1093/pan/mpq025> three-step estimators for latent class
        analysis ('LCA') 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 '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.
