术语“偏分布”的详细信息

英译术语:

skew distribution

汉语语境:

在地质数据中，许多数据常呈正偏或负偏分布，但并不服从对数或反对数正态分布。这时可考虑它们是否服从三参数对数或反对数正态分布。本文给出一种估计第三参数ｃ的方法。它可快速、客观、较优地确定此参数，弥补以往凭经验多次选择、反复试算等缺陷，为检验地质数据的统计分布型式，掌握分布规律，从而用于统计预测等提供了方便。

英语语境:

Any ggeological data often show positive(or negative)skew distributions but do not follow lognormal(or inverselognormal)distributions. In this case it is possible to consider whether they follow the lognormal(or inverse lognormal)distribution with three parameters. This paper proposes a new method for the optimal estimation of the third parameter c of these distributions. This method can estimate the third parameter c rapidly, objectively and optimally, so it is helpful to the statistical distribu-tion testing.
