This is an R package to predict one multi-way array (i.e., a tensor) from another multi-way array [1].
A stable version of the package is available from CRAN (link), which was checked and submitted by Bowen Li. This can be installed via install.packages("MultiwayRegression").
This version of the MultiwayRegression package can also be installed, directly from GitHub, using the devtools library:
install.packages("devtools")
library(devtools)
install_github("lockEF/MultiwayRegression")
library(MultiwayRegression)
