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.
