makediff2: 'Diffmatrix'

In survivalsvm: Survival Support Vector Analysis

Description

computes the matrix difference only between not censored data points (delta = 1). The data points are asssumed to be sorted by survival time and the difference is computed only if both the comparable data points are not censored.

Usage

makediff2(Y, delta)

Arguments

Y	[vector(1)] Ordered vector of survival times.
delta	[vector(1)] Vector of status

Value

[Diffmatrix(1)] Object of class Diffmatrix with elements:

Type	type of makediff function used to compute differences between neighbours.
Mat	matrix used to compute differences between comparable data points.

Examples

Y <- c(1,3,3.5,4,8); delta <- c(0,0,1,1,0); makediff2(Y, delta)
