makediff3: 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)

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.
