The probabilities are against us [in our favour]. 趋势对我们好像不利[有利]。 hit probability 命中率。 in all probability 很可能,大概,多半,十之八九。 probability of (missile survival) (飞弹不被击落的)概率。 The probability is that ... 大概是…,很可能是…。 There is every probability of [that] ... 多半有,多半会。 There is no probability of [that] ... 很难有,很难会。
This thesis mainly investigate the problem of confidence intervals of prescribed precision ( e . g . , the intervals " width ) and prescribed reliability controlled by coverage probability 本文主要讨论具任给精确度(区间长度)和可靠度(覆盖概率)的区间估计问题。
When the family of distributions satisfy some conditions , the confidence intervals of prescribed width and prescribed coverage probability could be obtained by two - stage procedures 当分布族满足一定条件时,用两步抽样即可获得具有预先给定长度与覆盖概率的置信区间。
When the parameter is fixed , sometimes the coverage probability may decrease with the increase of sample size , which is abnormal phenomenon , that is to say , there exists so called " unluky point " 当参数固定时,会出现样本量增加反而会使覆盖概率下降的反常现象,即存在所谓的“不幸点”问题。

In statistics, the coverage probability of a confidence interval is the proportion of the time that the interval contains the true value of interest.Dodge, Y.
