-
- These functions provide information about the chi-
- square distribution with df degrees of freedom. dchisq
- gives the density, pchisq gives the distribution func-
- tion qchisq gives the quantile function and rchisq gen-
- erates random deviates.
-
- The chi-square distribution with df = 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.
