Definition:G-Statistics

Definition

Let $S$ be a set of observations of a quantitative variable.

The $g$-statistics on $S$ are the statistical coefficients $g_1$ and $g_2$, defined as:

$g_1$ is the skewness $\gamma_1$ of the elements of $S$

$g_2$ is the kurtosis $\gamma_2$ of the elements of $S$.
