CoxBoost (version 1.5.1)

coef.CoxBoost: Coeffients from CoxBoost fit

Description

Extracts the coefficients from the specified boosting steps of a CoxBoost object fitted by CoxBoost.

Usage

# S3 method for CoxBoost
coef(object, at.step = NULL, scaled = TRUE, ...)

Value

For a vector of length p (number of covariates) (at.step being a scalar) or a length(at.step) * p matrix (at.step being a vector).

Arguments

object

fitted CoxBoost object from a CoxBoost call.

at.step

scalar or vector of boosting step(s) at which prediction is wanted. If no step is given, the final boosting step is used.

scaled

logical value indicating whether coefficients should be returned scaled to be at the level of the original covariate values, or unscaled as used internally when standardize=TRUE is used in the CoxBoost call.

...

miscellaneous arguments, none of which is used at the moment.
