Diffmatrix
Diffmatrixcomputes 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.
makediff2(Y, delta)
Y: [vector(1)]
Ordered vector of survival times.
delta: [vector(1)]
Vector of status
