中文摘要 | 本文章將回顧所謂的廣義偏斜t分佈和其分佈性質。接著利用兩獨立隨機變數相除,提出一個隸屬於廣義偏斜t分佈的一新子分佈族,並推導出其機率密度函數和各階動差的明確形式。此外,我們利用關於玻璃纖維的強度數據,來配適幾種廣義偏斜t分佈,以解釋這些分佈的彈性。最後,我們也會給出一些偏斜對稱分佈的性質。 |
英文摘要 | In this note, the so-called generalized skew-t distribution and some of its nice properties are reviewed. Then a new subclass of the generalized skew-t distribution through the ratio of two independent skew-symmetric ones is introduced, and its probability density function and explicit forms of moments are given. In addition, we illustrate the exibility of this class of distributions with applications to the strength data of glass fibres. Finally, properties of the skew-symmetric distribution are also investigated. |
