Description: An implementation of logistic normal multinomial (LNM)
        clustering. It is an extension of LNM mixture model proposed by
        Fang and Subedi (2020) <doi:10.1038/s41598-023-41318-8>, and is
        designed for clustering compositional data. The package
        includes 3 extended models: LNM Factor Analyzer (LNM-FA), LNM
        Bicluster Mixture Model (LNM-BMM) and Penalized LNM Factor
        Analyzer (LNM-FA). There are several advantages of LNM models:
        1. LNM provides more flexible covariance structure; 2. Factor
        analyzer can reduce the number of parameters to estimate; 3.
        Bicluster can simultaneously cluster subjects and taxa, and
        provides significant biological insights; 4. Penalty term
        allows sparse estimation in the covariance matrix. Details for
        model assumptions and interpretation can be found in papers: Tu
        and Subedi (2023) <doi:10.1007/s00357-023-09452-0> and Tu and
        Subedi (2022) <doi:10.3329/jsr.v56i2.67469>. It also include a
        Biclustering algorithm that applies to multivariate normal
        data: Tu and Subedi (2022) <doi:10.1002/sam.11555>.
