coef.StaPLR {mvs} | R Documentation |
Extract coefficients from a "StaPLR" object.
Description
Extract base- and meta-level coefficients from a "StaPLR" object at the CV-optimal values of the penalty parameters.
Usage
## S3 method for class 'StaPLR'
coef(object, cvlambda = "lambda.min", ...)
Arguments
object |
Fitted "StaPLR" model object. |
cvlambda |
By default, the coefficients are extracted at the CV-optimal values of the penalty parameters. Choosing "lambda.1se" will extract them at the largest values within one standard error of the minima. |
... |
Further arguments to be passed to |
Value
An object with S3 class "StaPLRcoef".
