order of central momentum


The common assumption is that zero-th central momentum is unit-value: 

LaTeX Math Inline
body\mu_0 \equiv 1
.

By definition the first central momentum is always zero: 

LaTeX Math Inline
body\mu_1 \equiv 0
.

Second central momentum (μ2) is called variance

LaTeX Math Inline
body--uriencoded--\mu_2 = \sigma%5e2
, where 
LaTeX Math Inline
body\sigma
 is standard deviation.
