survivalsvm (version 0.0.6)

makediff2: Diffmatrix

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)

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.

Arguments

Y

[vector(1)]
Ordered vector of survival times.

delta

[vector(1)]
Vector of status
