%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. References: Satoh
