Description Usage Arguments Value See Also Examples

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

1
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.
