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.
