Jane Liang has written three interconnected packages for implementing matrix linear models in Julia.

A brief introduction to matrix linear models

• matrixLM.jl is the base package that implements matrix linear models of the form $Y = X B Z^' + E$.
• GeneticScreen.jl implements pre- and post-processing for the analysis of high-throughput genetic screens using matrix linear mo0dels.
• matrixLMnet.jl implements functions to obtain L$_1$-penalized estimates for matrix linear models.
