In rpsftm: Rank Preserving Structural Failure Time Models

Extracting the z-statistic from a survival object

Description

Generic S3 methods to extract the z-statistic from a set of survival fit objects

Usage

extract_z(fit, ...)

## S3 method for class 'survdiff'
extract_z(fit, ...)

## S3 method for class 'coxph'
extract_z(fit, arm, ...)

## S3 method for class 'survreg'
extract_z(fit, arm, ...)

Arguments

fit	a fitted survival object : survdiff, coxph, survreg
...	extendible arguments to the S3 method
arm	a character vector giving the name of the covariate representing the treatment arm.

Value

a numeric value, the z statistic for the independence test of the treatment arm

Methods (by class)

• extract_z(survdiff): Method for survdiff

• extract_z(coxph): Method for coxph objects

• extract_z(survreg): Method for survreg objects
