summary.stdParfrailty {stdReg}

Summarizes Frailty standardization fit

Description

This is a summary method for class "stdParfrailty".

Usage

## S3 method for class 'stdParfrailty'
summary(object, t, CI.type = "plain", CI.level = 0.95,
  transform = NULL, contrast = NULL, reference = NULL, ...)

Arguments

object

an object of class "stdParfrailty".

t

numeric, indicating the times at which to summarize. It defaults to the specified value(s) of the argument t in the stdCox function.

CI.type

string, indicating the type of confidence intervals. Either "plain", which gives untransformed intervals, or "log", which gives log-transformed intervals.

CI.level

desired coverage probability of confidence intervals, on decimal form.

transform

a string. If set to "log", "logit", or "odds", the standardized survival function \theta(t,x) is transformed into \psi(t,x)=log\{\theta(t,x)\}, \psi(t,x)=log[\theta(t,x)/\{1-\theta(t,x)\}], or \psi(t,x)=\theta(t,x)/\{1-\theta(t,x)\}, respectively. If left unspecified, \psi(t,x)=\theta(t,x).

contrast

a string. If set to "difference" or "ratio", then \psi(t,x)-\psi(t,x_0) or \psi(t,x) / \psi(t,x_0) are constructed, where x_0 is a reference level specified by the reference argument.

reference

must be specified if contrast is specified.

...

not used.
