Skew-normal distributionSkew scale mixtures of normal distributionsNormal nonlinear regression models are applied in some areas of the sciences and engineering to explain or describe the phenomena under study. However, it is well known that several phenomena are not always represented by the normal ...
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 [...

Two characterization results for the skew-normal distribution based on quadratic statistics have been obtained. The results specialize to known characterizations of the standard normal distribution and generalize to the characterizations of members of a larger family of distributions. Results on the decompos...
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 ...
Given a set of data, one of the statistical issues is to see how well the data fit into a postulated model. This technique necessitates the corresponding table of the probability distribution for the proposed model. In this paper, we present the table for skew normal distributions with differe...
The non-infinite divisibility of some skewed distributions generated by the normal kernel,which includes skew normal-normal,skew normal-Cauchy andskew normal-uniform distribution,are investigated. 给出了无穷可分分布的一个必要条件;讨论了斜正态-正态分布、斜正态-Cauchy分布和斜正态-均匀分布这3类正态核...
