WebMay 30, 2016 · 二、P值（P value）就是当原假设为真时所得到的样本观察结果或更极端结果出现的概率。如果P值很小，说明原假设情况的发生的概率很小，而如果出现了，根据小概率原理，我们就有理由拒绝原假设，P值越小，我们拒绝原假设的理由越充分。 WebIf the P value is small enough (smaller than the specified alpha level, generally set to 0.05), then the null hypothesis (that the parameter estimate is zero) is rejected. For these tests, we always generate two-sided (two-tailed) P values, since we’d be equally interested in parameter estimates that were greater or less than zero (or hazard ...
