Summarizing inferences based on cross-validation

Description

Summary method for cv.biglasso objects.

Usage

## S3 method for class 'cv.biglasso'
summary(object, ...)

## S3 method for class 'summary.cv.biglasso'
print(x, digits, ...)

Arguments

object	A cv.biglasso object.
...	Further arguments passed to or from other methods.
x	A "summary.cv.biglasso" object.
digits	Number of digits past the decimal point to print out. Can be a vector specifying different display digits for each of the five non-integer printed values.

Value

summary.cv.biglasso produces an object with S3 class "summary.cv.biglasso". The class has its own print method and contains the following list elements:

penalty	The penalty used by biglasso.
model	Either "linear" or "logistic", depending on the family option in biglasso.
n	Number of observations
p	Number of regression coefficients (not including the intercept).
min	The index of lambda with the smallest cross-validation error.
lambda	The sequence of lambda values used by cv.biglasso.
cve	Cross-validation error (deviance).
r.squared	Proportion of variance explained by the model, as estimated by cross-validation.
snr	Signal to noise ratio, as estimated by cross-validation.
sigma	For linear regression models, the scale parameter estimate.
pe	For logistic regression models, the prediction error (misclassification error).
