Description: Performs Non-negative Matrix Factorization (NMF)
    with Kernel Covariates. Given an observation matrix and kernel
    covariates, it optimizes both a basis matrix and a parameter matrix.
    Notably, if the kernel matrix is an identity matrix, the method
    simplifies to standard NMF. Also provides NMF with Random Effects
    (NMF-RE) via nmfre(), which estimates a mixed-effects model combining
    covariate-driven scores with unit-specific random effects together
    with wild bootstrap inference, and NMF-based Structural Equation
    Modeling (NMF-SEM) via nmf.sem(), which fits a two-block input-output
    model for blind source separation and path analysis.
