rank {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.
