是的，当你做t-test的时候，p-value跟你的t-statistic 的值是对应的。因为p－value的意义是取到t-statistic的概率。
.y.: the y variable used in the test. group1,group2: the compared groups in the pairwise tests. statistic: Test statistic used to compute the p-value. df: degrees of freedom. p: p-value. Note that, you can obtain a detailed result by specifying the option detailed...
The test statistic is2=0.53-0.5=1.921027As shown in Display 8.18, the P-value of 0.0274 is the probability of getting a test statistic greater than 1.92 if the null hypothesis is true.0.02747=197Display 8.18 The P-value for the successful life/friends problem. ...
A p-value can be computed for the corresponding absolute value of t-statistic (|t|). Note that, the Welch t-test is considered as the safer one. Usually, the results of the classical t-test and the Welch t-test are very similar unless both the group sizes and the standard deviations...
p-value :A p-value is the probability of obtaining a test statistic at least as extreme as the one that was observed, assuming that Ho is true. 什么是 p 值呢?它是一个概率值。如果零假设为真,现有的检验统计量出现的概率就是 p-value。

不知道大家平时用的时候有没有注意到其中一些参数的设置,例如correct = TRUE,rescale.p = FALSE 以及 simulate.p.value = FALSE 以下附上代码参数的官方解释,并对各参数的使用进行详细阐述: correct: a logical indicating whether to apply continuity correction when computing the test statistic for 2 by 2 ta...
[h,pValue] = waldtest(___) returns the p-value of the hypothesis test, using any of the input arguments in the previous syntaxes. example [h,pValue,stat,cValue] = waldtest(___) returns the test statistic and critical value of the hypothesis test. exampleExamples...
