Diffmatrix
DiffmatrixThe 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.
makediff3(Y, delta)
Y: [vector(1)]
Ordered vector of survival times.
delta: [vector(1)]
Vector of status.
[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. |
Y <- c(1,3,3.5,4,8); delta <- c(0,0,1,1,0); makediff3(Y, delta)
