The basic theory of literature selection is that select those literatures whose probability use-value is higher at the same cost.
文献选择是文献采集的核心，文献选择的基本原理是在成本相同的情况下，优先选择概率使用价值大的文献。
In practice, I don't use such graphs to compute tail probabilities because I can implement mathematical functions to return the tail probability for a given Chi Square value.
实际上，我不使用这些图来计算尾数概率，因为我可以实现数学函数来返回给定x平方分布值的尾数概率。
Another important concept in probability theory that we will use a lot is expected value, the mean, or average — those are all roughly interchangeable concepts.
概率论中另外一个常用的重要的概念是，期望值或者也叫均值，这两个概念可以互换。
