To perform main effect matrix factor model (MEFM) estimation for a given matrix time series as described in Lam and Cen (2024) <doi:10.48550/arXiv.2406.00128>. Estimation of traditional matrix factor models is also supported. Supplementary functions for testing MEFM over factor models are included.

Uses as input genetic data that have been reformatted and
     stored in a 'SQLite' database; this database is initially created
     by the standalone 'mega2' C++ program (available freely from
     <https://watson.hgen.pitt.edu/register/>). Loads and manipulates
     data frames containing genotype, phenotype, and family
     information from the input 'SQLite' database, and decompresses
     needed subsets of the genotype data, on the fly, in a memory
     efficient manner.  We have also created several more functions
     that illustrate how to use the data frames as well as perform
     useful tasks: these permit one to run the 'pedgene' package to
     carry out gene-based association tests on family data using
     selected marker subsets, to run the 'SKAT' package to carry out
     gene-based association tests using selected marker subsets, to
     run the 'famSKATRC' package to carry out gene-based association
     tests on families (optionally) and with rare or common variants
     using selected marker subsets, to output the 'Mega2R' data as a
     VCF file and related files (for phenotype and family data), and
     to convert the data frames into CoreArray Genomic Data Structure
     (GDS) format.
