makediff1: 'Diffmatrix'

In imbs-hl/survivalsvm: Survival Support Vector Analysis

Description

The data points are asssumed to be sorted by survival time. The comparison only takes place between two consecutivee observations when the first one is not censored (delta = 1).

Usage

makediff1(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); makediff1(Y, delta)
