predict.cv.sparsegl: Make predictions from a 'cv.sparsegl' object.

In hierNest: Penalized Regression with Hierarchical Nested Parameterization Structure

Make predictions from a 'cv.sparsegl' object.

Description

This function makes predictions from a cross-validated [cv.sparsegl()] object, using the stored 'sparsegl.fit' object, and the value chosen for 'lambda'.

Usage

## S3 method for class 'cv.sparsegl'
predict(
  object,
  newx,
  s = c("lambda.1se", "lambda.min"),
  type = c("link", "response", "coefficients", "nonzero", "class"),
  ...
)

Arguments

object	Fitted [cv.sparsegl()] object.
newx	Matrix of new values for 'x' at which predictions are to be made. Must be a matrix. This argument is mandatory.
s	Value(s) of the penalty parameter 'lambda' at which coefficients are desired. Default is the single value 's = "lambda.1se"' stored in the CV object (corresponding to the largest value of 'lambda' such that CV error estimate is within 1 standard error of the minimum). Alternatively 's = "lambda.min"' can be used (corresponding to the minimum of cross validation error estimate). If 's' is numeric, it is taken as the value(s) of 'lambda' to be used.
type	Type of prediction required. Type '"link"' gives the linear predictors for '"binomial"'; for '"gaussian"' models it gives the fitted values. Type '"response"' gives predictions on the scale of the response (for example, fitted probabilities for '"binomial"'); for '"gaussian"' type '"response"' is equivalent to type '"link"'. Type '"coefficients"' computes the coefficients at the requested values for 's'. Type '"class"' applies only to '"binomial"' models, and produces the class label corresponding to the maximum probability. Type '"nonzero"' returns a list of the indices of the nonzero coefficients for each value of s.
...	Not used.

Value

A matrix or vector of predicted values.
