We propose a new approximate skew normal distribution, it is easy to calculate, convenient, mathematically tractable and is in a closed form it is particularly useful when the probability density function occurs in an expression to be used for further mathematical derivation or in programs for the skew normal distribution also.

Skew is a relatively new area of research in academic finance, and people quite often use the standard skew measure (third moment) without too much thought this is an issue, and it would be useful to move towards a new metric which would be robust to estimation and also useful to investors ns: it is important to keep in. Although the normal probability distribution is the cornerstone of applying statistical methodology data do not always meet the necessary normal distribution assumptions in these cases, researchers often transform non-normal data to a distribution that is approximately normal power transformations.
