shrink.coxph R Documentation
Global, Parameterwise and Joint Shrinkage of Regression Coefficients for Fit Object's of Class coxph.
Description
Internal function for shrink.
Usage
shrink.coxph(fit, type, method, join, notes, postfit)
Arguments
fit
a fit object of class lm, glm, coxph, or mfp.
The fit object must have been called with x = TRUE (and
y = TRUE in case of class lm).
type
of shrinkage, either "parameterwise" (default), "global"
shrinkage, or "all".
method
of shrinkage estimation, either "jackknife" (based on
leave-one-out resampling, default) or "dfbeta" (excellent approximation
based on DFBETA residuals).
join
compute optional joint shrinkage factors for sets of specified columns
of the design matrix, if type = "parameterwise". See details.
notes
print notes. Default is TRUE.
postfit
obtain fit with shrunken regression coefficients. This option
is only available for models without an intercept. Default is TRUE.
Value
A list with the following elements
ShrinkageFactors cdot
ShrinkageFactorsVCOV sfit$var
ShrunkenRegCoef cdot * beta
postfit pfit
