- These functions provide information about the non-
- central chi-square distribution with df degrees of
- freedom. dnchisq gives the density, pnchisq gives the
- distribution function qnchisq gives the quantile func-
- tion and rnchisq generates random deviates.
-
- The non-central chi-square distribution with n
- degrees-of-freedom has density
-
- f(x) = 1 / (2^(n/2) Gamma(n/2)) x^(n/2-1) e^-x/2
-
- for x >= 0.
