rowKurtosis#
- swordfish.function.rowKurtosis()#
Return the kurtosis of each row in X.
The calculation uses the following formula when biased=true:
\[\begin{align*} \operatorname{kurtosis}(x) &= \frac{\displaystyle \frac{1}{n}\sum_{i=1}^n (x_i-\bar{x})^4} {\displaystyle\left(\frac{1}{n}\sum_{i=1}^n (x_i-\bar{x})^2\right)^2} \end{align*}\]
