Return the *n*th centralized moment of a distribution.

## 📄️ Tail Probability

Return the tail probability of a distribution beyond a cut-off value.

## 📄️ Quantile

Return the quantile of a distribution for a given probability value.

## 📄️ Distributional Support Minimum

Return the minimum of the support of a distribution.

## 📄️ Distributional Support Maximum

Return the maximum of the support of a distribution.
