Description: Fits spatial mixture models, including spatial Gaussian mixtures
    and mixtures of spatial factor analyzers, to complete or
    incomplete data. Spatial decay can be represented by monotone I-splines or
    a normalized sigmoid. Missing entries are handled using a built-in partial
    expectation-maximization procedure for matrix-variate data. The spatial
    covariance and spatial factor analyzer models are described in Lu and
    colleagues (2026a)
    "Spatial Covariance Constraints for Gaussian Mixture Models"
    <doi:10.48550/arXiv.2601.07979> and Lu and colleagues (2026b) "Mixtures of
    spatial factor analyzers for tensor-variate data"
    <doi:10.48550/arXiv.2607.07887>.
