MatrixLM

This package can estimates matrix linear models. The core functions to obtain closed-form least squares estimates for matrix linear models. Variance shrinkage is adapted from Ledoit & Wolf (2003).

An extension of MatrixLM for applications in high-throughput genetic screens is the GeneticScreens package. See the associated paper, "Matrix linear models for high-throughput chemical genetic screens", and its reproducible code for more details.

MatrixLMnet is a related package that implements algorithms for L1-penalized estimates for matrix linear models. See the associated paper, "Sparse matrix linear models for structured high-throughput data", and its reproducible code for more details.

The MatrixLM package can be installed by running:

using Pkg
Pkg.add("MatrixLM")

For the most recent version, use:

using Pkg
Pkg.add(url = "https://github.com/senresearch/MatrixLM.jl", rev="main")

Alternatively, you can also install MatrixLM from the julia REPL. Press ] to enter pkg mode again, and enter the following:

add MatrixLM
