In remss: Refining Evaluation Methodology on Stage System

Description

rank returns five measurements for the grouping scheme and its overall rank.

Usage

rank(os, ostime, groupvar, scheme, order, covariate, weight, data)

Arguments

os	Survival indicator, 1 for death, 0 for censoring.
ostime	Duration time of survival.
groupvar	Basic group variable having the most number of stages.
scheme	Different grouping scheme, which has less stages than the basic group variable.
order	The other of stages in each grouping, from
covariate	Covariate variables taking into consideration.
weight	Weight on five measurements of grouping scheme.
data	Data set.

Value

Ranking of five measurements, which are Hazard consistency, Hazard discrimination, Explained variation, Likelihood difference and Balance. By standardized each measurement score, we provides overall ranking of schemes.
