glmnet (version 4.1-8)

print.cv.glmnet: print a cross-validated glmnet object

Description

Print a summary of the results of cross-validation for a glmnet model.

Usage

# S3 method for cv.glmnet
print(x, digits = max(3, getOption("digits") - 3), ...)

Arguments

x

fitted 'cv.glmnet' object

digits

significant digits in printout

...

additional print arguments

Author

Maintainer: Trevor Hastie

Details

A summary of the cross-validated fit is produced, slightly different for a 'cv.relaxed' object than for a 'cv.glmnet' object. Note that a 'cv.relaxed' object inherits from class 'cv.glmnet', so by directly invoking print.cv.glmnet(object) will print the summary as if relax=TRUE had not been used.

Examples

x = matrix(rnorm(100 * 20), 100, 20)
y = rnorm(100)
fit1 = cv.glmnet(x, y)
print(fit1)
fit1r = cv.glmnet(x, y, relax = TRUE)
print(fit1r)
