High-dimensional multi-study multi-modality covariate-augmented generalized factor model
=========================================================================
Latent factor models that integrate data from multiple sources/studies or modalities have garnered considerable attention across various disciplines. However, existing methods predominantly focus either on multi-study integration or multi-modality integration, rendering them insufficient for analyzing the diverse modalities measured across multiple studies. To address this limitation and cater to practical needs, we introduce a high-dimensional generalized factor model that seamlessly integrates multi-modality data from multiple studies, while also accommodating additional covariates.

"MMGFM" depends on the 'Rcpp' and 'RcppArmadillo' package, which requires appropriate setup of computer. For the users that have set up system properly for compiling C++ files, the following installation command will work.
## Method 1：
if (!require("remotes", quietly = TRUE))
install.packages("remotes")
remotes::install_github("feiyoung/MMGFM")
## Method 2: install from CRAN
install.packages("MMGFM")
