docs: Indices of columns where p < alpha for column-comparison t-tests
  
          Returns an array of tuples of columns that are significant at p<alpha,
          from a series of pairwise t-tests.
  
          Argument both_pairs returns indices striclty on the test statistic. If
          False, however, only the index of values *significantly smaller* than
          each cell are indicated.
