Package for L1 and L2 penalized estimation of matrix linear models (bilinear models for matrix-valued data).

MatrixLMnet depends on the MatrixLM package, which provides core functions for closed-form least squares estimates for matrix linear models.

See the paper, "Sparse matrix linear models for structured high-throughput data", and its reproducible code for details on the L1 penalized estimation.

The MatrixLMnet package can be installed by running:

using Pkg
Pkg.add("MatrixLMnet")

For the most recent version, use:

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

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

add MatrixLMnet
