sdwd (version 1.0.5)

print.sdwd: print an sdwd object

Description

Print a summary of the sdwd solution paths.

Usage

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

Arguments

x

A fitted sdwd object.

digits

Specify the significant digits.

…

Additional print arguments.

Value

A two-column matrix with one column of the number of nonzero coefficients and a second column of lambda values.

Details

This function prints a two-column matrix with columns Df and Lambda, where the Df column exhibits the number of nonzero coefficients and the Lambda column displays the corresponding lambda value. This function is modified based on the print function from the gcdnet and the glmnet packages.
