phreg: Fast Cox PH regression

Description

Fast Cox PH regression Robust variance is default variance with the summary.

Usage

phreg(formula, data, offset = NULL, weights = NULL, ...)

Arguments

formula

formula with 'Surv' outcome (see coxph)

data

data frame

offset

offsets for cox model

weights

weights for Cox score equations

...

Additional arguments to lower level funtions

Examples

# NOT RUN {
data(TRACE)
dcut(TRACE) <- ~.
out1 <- phreg(Surv(time,status==9)~vf+chf+strata(wmicat.4),data=TRACE)
## tracesim <- timereg::sim.cox(out1,1000)
## sout1 <- phreg(Surv(time,status==1)~vf+chf+strata(wmicat.4),data=tracesim)
## robust standard errors default 
summary(out1)

par(mfrow=c(1,3))
basehazplot.phreg(out1)
## basehazplot.phreg(sout1,se=TRUE)

## computing robust variance for baseline
rob1 <- robust.phreg(out1)
basehazplot.phreg(rob1,se=TRUE,robust=TRUE)

## making iid decomposition of regression parameters
betaiiid <- iid(out1)

# }
