Quantlet: cdfchi2
Description: Cdfchi2 returns the values of the chi-square distribution function with d degrees of freedom for the elements of an array.

Usage: y=cdfchi2(x,d)
Input:
x input array
d a scalar or an array of the same dimension as x containing the number of degrees of freedom for chi-square distribution
Output:
y output array, it contains the values of the specified chi-square distribution function for the elements of array x

Note:

Example:
library("distribs")
a=#(0.5, 0.4)~#(0.01, 1)~#(-1,2)
cdfchi2(a, 6)

Result:
