Description

Looks at stratified baseline in Cox model and plots all baselines versus each other to see if lines are straight, with 50 resample versions under the assumptiosn that the stratified Cox is correct

Usage

gofG.phreg(x, sim = 0, silent = 1, lm = TRUE, ...)

Arguments

`x`	phreg object
`sim`	to simulate som variation from cox model to put on graph
`silent`	to keep it absolutely silent
`lm`	addd line to plot, regressing the cumulatives on each other
`...`	Additional arguments to lower level funtions

Examples

data(TRACE)

m1 <- phreg(Surv(time,status==9)~strata(vf)+chf+wmi,data=TRACE) 
m2 <- phreg(Surv(time,status==9)~vf+strata(chf)+wmi,data=TRACE) 
par(mfrow=c(2,2))

gofG.phreg(m1)
gofG.phreg(m2)

bplot(m1,log="y")
