Joint location and scale models of the skew-normal distribution provide useful extension for joint mean and variance models of the normal distribution when the data set under consideration involves asymmetric outcomes. This paper focuses... LI Hui-Qiong,WU Liu-Cang,DO Statistics,... - 《高校应用...
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...

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...
) 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 ) or lighter than normal (when ). It is a useful way to parametrize a continuum of symmetric, platykurtic...
Further, some patients will drop outas time progresses, so the scores reflect a selected population.We fit models based on the skew-normal distribution to data from a randomised controlled trial of treatments for sprained ankles, in which scores were recorded at baselineand 1, 3 and 9 months....
