This R package offers a general framework of multivariate mixed-effects models for the joint analysis of multiple correlated outcomes with clustered data structures and potential missingness proposed by Wang et al. (2018) doi:10.1093/biostatistics/kxy022. The missingness of outcome values may depend on the values themselves (missing not at random and non-ignorable), or may depend on only the covariates (missing at random and ignorable), or both. This package provides functions for two models:
- mvMISE_b allows correlated outcome-specific random intercepts with a factor-analytic structure;
- mvMISE_e allows the correlated outcome-specific error terms with a graphical lasso penalty on the error precision matrix.
Both functions are motivated by the multivariate data analysis on data with clustered structures from labelling-based quantitative proteomic studies. These models and functions can also be applied to univariate and multivariate analyses of clustered data with balanced or unbalanced design and no missingness.
