Description: Computes the penalized maximum likelihood estimates of
        factor loadings and unique variances for various tuning
        parameters. The pathwise coordinate descent along with EM
        algorithm is used.  This package also includes a graphical tool
        which outputs path diagrams, heatmaps, goodness-of-fit indices
        and model selection criteria for each regularization parameter
        (Yamamoto, M., Hirose, K. and Nagata, H., 2017
        <doi:10.1007/s41237-016-0007-3>). The user can change the
        regularization parameter interactively with a built-in
        self-contained HTML viewer (no additional packages required),
        which is helpful to find a suitable value of regularization
        parameter. As a penalty, we can choose either the minimax
        concave penalty (Hirose, K. and Yamamoto, M., 2015
        <doi:10.1007/s11222-014-9458-0>; Hirose, K. and Yamamoto, M.,
        2014 <doi:10.1016/j.csda.2014.05.011>) or the product-based
        elastic net penalty (Hirose, K. and Terada, Y., 2023
        <doi:10.1007/s11336-022-09868-4>).
