skew normal distribution is a continuous probability distribution that generalises the normal distribution to allow for non- zero skewness.Contents 1 Definition 2 Estimation 3 Differential equation 4 See also 5 References 6 External links Definition Let denote the standard normal probability density ...
A note on skew-normal distribution approximation to the negative binomal distribution This article revisits the problem of approximating the negative binomial distribution. Its goal is to show that the skew-normal distribution, another alter... R Jou,Chinghui Chang,JJ Lin - 《Wseas Transactions on...
It is possible to fit the generalized normal distribution adopting an approximate maximum likelihood method.[4][5]With initially set to the sample first moment , is estimated by using a Newton–Raphson iterative procedure, starting from an initial guess of ...
A class of power series skew normal distributions is introduced by generalizing the geometric skew normal distribution of Kundu [Sankhyā B, 76, 2014, 167-189]. Various mathematical properties are derived and estimation addressed by the method of maximum likelihood. The data application of Kundu [...
This family includes the normal distribution when (with mean and variance ) and it includes the Laplace distributionwhen . As , the density converges pointwise to a uniform density on . This family allows for tails that are either heavier than normal (when ...
The paper extends earlier work on the so-called skew-normal distribution, a family of distributions including the normal, but with an extra parameter to regulate skewness. The present work introduces a multivariate parametric family such that the marginal densities are scalar skew-normal, and studies...
This article is related with the probabilistic and statistical properties of an parametric extension of the so-called epsilon-skew-normal (ESN) distribution introduced by Mudholkar and Hutson (2000), which considers an additional shape parameter in order to increase the flexibility of the ESN distrib...
