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 with feed-forward and feedback structure
        (NMF-FFB) via nmf.ffb(), which fits a two-block input-output
        model for blind source separation and path analysis.
