mean_chi2

Maxima Function

Calling Sequence

mean_chi2 (n)

Description

Returns the mean of a Chi-square random variable Chi^2(n), with n>0.

The Chi^2(n) random variable is equivalent to the Gamma(n/2,2), therefore when Maxima has not enough information to get the result, a noun form based on the gamma mean is returned.
