Macro: hazard
Description: Nonparametric estimator of the hazard rate. The bandwidth parameter can be optionally chosen.

Reference(s):

Usage: h = hazard (y {,bandwidth})
Input:
y n x 2 matrix
bandwidth scalar
Output:
h vector

Note:

Example:
;Nonparametric estimator of the hazard rate for the leukaemia 
; data, by using the default grid.
; loads the library stats 
library("stats")
x = read("leukaemia.dat")
h = hazard(x)
h
Result:
