This package provides functions for computing the split regularized regression estimators defined in Christidis, Lakshmanan, Smucler and Zamar (2019).
You can install the stable version on R CRAN.
You can install the development version from GitHub
# A small example
library(MASS)
library(SplitReg)
set.seed(1)
beta <- c(rep(5, 5), rep(0, 45))
Sigma <- matrix(0.5, 50, 50)
diag(Sigma) <- 1
x <- mvrnorm(50, mu = rep(0, 50), Sigma = Sigma)
y <- x %*% beta + rnorm(50)
fit <- cv.SplitReg(x, y, num_models=10) # Use 10 models
coefs <- predict(fit, type="coefficients")
