Critical values for test statistic based on all intervalscvModeAll
选择合适统计量,依赖于你的假设对象,比较两个均值是选择Z-test或t-test,或检验两个类别型变量的独立性选择Fisher检验或chi-square检验。 选择显著性水平,通常是0.05,或0.01 确定在显著水平下用来拒绝零假设的critical value 计算检验统计值 test statistic 比较test statistic 和 critical value P-value:被用于评价零...
Following a procedure applied to the Erlang-2 distribution in a recent paper, an adjusted KolmogorovSmirnov statistic and critical values are developed for the Erlang-3 and -4 cases using data from Monte Carlo simulations. The test statistic produced features of compactness and ease of implementation...

比较critical value 和 test statistic的大小 Hypothesis Testing (P-value approach) P-value代表的是一个概率,它假设null hypothesis是True的情况下,在alternative hypothesis方向上出现一个比我们sample data的test statistic更极端的test statistic的概率。如果P-value是小于(或等于)α,那么null hypothesis is rejected...
