makediff3: 'Diffmatrix'

In imbs-hl/survivalsvm: Survival Support Vector Analysis

Diffmatrix

Description

The first observation is assumed to be not censored (delta = 1). The Difference is computed between data point i and its neighbour that has the largest survival time but smaller than y_i, the survival time of i.

Usage

makediff3(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); makediff3(Y, delta)
