It avoided the notion of space and time by replacing it with abstract mathematical properties of the S -matrix. In S -matrix theory, the S -matrix relates the infinite past to the infinite future in one ...
The permutation test is designed to determine whether the observed difference between the sample means is large enough to reject, at some significance level, the null hypothesis H that the data drawn from is from the same distribution as the data drawn from . The test proceeds as follows. First, the difference in means between the two samples ...
