چکیده | ||
In this article, first a density by the name ”The bimodal standard normal density” is introduced and denoted by $b\varphi(z)$. Then, a definition for the kurtosis of bimodal densities relative to $b\varphi(z)$ is presented. Finally, to illustrate the introduced kurtosis, a few examples are provided and a real data set is studied, too. | ||
