Maxima Function

Calling Sequence

skewness_exp (m)

Description

Returns the skewness coefficient of an Exponential(m) random variable, with m>0.

The Exponential(m) random variable is equivalent to the Weibull(1,1/m), therefore when Maxima has not enough information to get the result, a noun form based on the Weibull skewness coefficient is returned.
