Description
The pair-sample t-test analysis tests whether or not the means of two paired (or related, matched) samples from a normal distribution are equal or whether they differ by a given value.
This function performs pair-sample t-test for the rows. The data of both samples is set in one row to perform the pair-sample t-test of this row.
