logrank_IPSW_RISCA: Calculate median survival time

In MBender1992/emR: Dictionary for EuMelaReg functions (analysis of clinical studies)

Calculate median survival time

Description

The user enters individual survival data and the weights previously calculated (by using logistic regression for instance). The usual log-rank test is adapted to the corresponding adjusted survival curves.

Usage

logrank_IPSW_RISCA(time, status, var, weights = NULL)

Arguments

time	A numeric vector with the follow up time.
status	A numeric vector with the event indicator (0=right censored, 1=event).
var	A numeric vector with the binary var under interest (only two groups).
weights	The weights for correcting the contribution of each individual. By default, the weights are all equaled to 1 and the survival curves correspond to the usual Kaplan-Meier estimator.
