centred moment
Definition
- For a given positive natural number k, the k-th central moment of a random variable x is defined as k=E[(x−E[x])k]. That is, it is the expected value of the deviation from the mean to the power k. In particular, 0=1, 1=0 and 2 is the variance of x. [UncertML] http://www.uncertml.org/statistics/centred-moment
