This feature is called skewness. In order to quantify it, we have something called the coefficient of skewness. Webb31 dec. 2015 · 1 Answer. You can use the skew normal distribution with parameters ( ξ, ω, α) which can be estimated from the given data. If we set δ = α 1 + α 2, then the mean, variance and skewness of the skew normal distribution are given by (see the link) Substitute your known values for the mean, variance and skewness to find proper values …
