Central Moment
In probability theory and statistics, central moments form one set of values by which the properties of a probability distribution can be usefully characterised. Central moments are used in preference to ordinary moments because then the values' higher-order quantities relate only to the spread and shape of the distribution, rather than to its location.
Sets of central moments can be defined for both univariate and multivariate distributions.

“My solitaria
Are the meditations of a central mind.
I hear the motions of the spirit and the sound
Of what is secret becomes, for me, a voice
That is my own voice speaking in my ear.”
