| basehaz {survival} | R Documentation |
Compute the baseline survival curve for a Cox model.
basehaz(fit, centered = TRUE)
fit |
The result of a coxph fit. |
centered |
If TRUE, the resultant curve is for a hypothetical subject whose covariate values are the corresponding means from the original data, otherwise for a hypothetical subject with a mean vector of zero. |
This function exists primarily because users will look for the phrase
'baseline hazard' (often SAS converts looking for familiar
keywords.) The primary function for creating a survival curve is
survfit, which this calls. See that manual page for more
options, including confidence limits and the ability to use other
covariate vectors. The result of survfit also has print, plot
and summary methods that make it far more useful.
a data frame with components
time |
The sorted vector of unique time points (those at which an event occurred |
hazard |
The baseline hazard function |
strata |
If fit was a stratified Cox model, the strata.
There will be one survival curve per strata. |
