Description: Variational Bayes estimation for a family of psychometric
        measurement models. Two models are provided. Variational Bayes
        factor analysis (vbfa) is a regularized partially confirmatory
        factor model spanning the confirmatory-exploratory continuum
        via spike-and-slab priors on the loadings (Chen, Guo, Zhang,
        and Pan, 2021 <doi:10.1037/met0000293>; Chen, 2023
        <doi:10.3758/s13428-022-01884-7>; Jin and Chen, 2025
        <doi:10.1080/10705511.2024.2432612>), with an optional dynamic
        (warm-started) regularization path, an orthogonal bifactor
        parameterization, and optional sparse residual (local
        dependence) estimation through a graphical spike-and-slab prior
        solved by QUIC (Jin, Chen, Yan, and Zhang, 2026
        <doi:10.31234/osf.io/dehtv_v2>). Regularized MIMIC (vbmimic)
        extends this to multiple-indicators multiple-causes models,
        placing spike-and-slab priors on both the measurement and the
        structural part (Jin and Chen, 2025
        <doi:10.1080/00273171.2025.2483253>). Companion tools compute
        SEM-like fit statistics, and sweep a factor-count window to
        report candidate fit, criterion, and between-candidate
        loading-correspondence measurements without selecting a count
        (Chen and Jin, 2026 <doi:10.48550/arXiv.2607.07159>). Data
        generators for either model family are also provided.
