A set of statistical metrics, characterizing the average deviation of the numerical values in the given dataset
A set of statistical metrics, characterizing the average deviation of the numerical values in the given dataset from its Mean Value
:
\bar \mu_n = \frac{\mu_n}{\sigma^n}, \ \ n \geq 3 |
where
n-order of central momentum | |
The concept makes sense only for the central momentums of higher oder than , since lower order central momentums
,
,
are trivial and do not carry additional information on dataset distribution.
The most popular application is the 3-rd order standardized central momentum , which is called skewness and characterizes asymmetry of the dataset distribution.
