Syntax

dchisq(x, df)
pchisq(x, df)
qchisq(x, df)
rchisq(x, df)

Value

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

The chi-square distribution with n degrees of freedom has density
