Quantlet: cdfncchi2
Description: Cdfncchi2 returns the values of the noncentral chi-square distribution function with d degrees of freedom and the parameter of noncentrality l for the elements of an array.

Usage: y = cdfncchi2(x, d{, l})
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
l a scalar or an array of the same dimension as x containing the value for the parameter of noncentrality for noncentral chi-square distribution; if not specified, l = 0 is used
Output:
y output array, it contains the values of the specified noncentral chi-square distribution function for the elements of array x

Note:

Example:
library("distribs")
a=#(0.5, 0.4)~#(0.01, 1)~#(-1,2)
cdfncchi2(a, 6, 2)

Result:
