docs: Return continuous random values for each record pair.
  
          Parameters
          ----------
          pairs : pandas.MultiIndex
              A pandas MultiIndex with the record pairs to compare. The indices
              in the MultiIndex are indices of the DataFrame(s) to link.
          x : pandas.DataFrame
              The DataFrame to link. If `x_link` is given, the comparing is a
              linking problem. If `x_link` is not given, the problem is one of
              deduplication.
          x_link : pandas.DataFrame, optional
              The second DataFrame.
  
          Returns
          -------
          pandas.Series, pandas.DataFrame, numpy.ndarray
              The result of comparing record pairs (the features). Can be
              a tuple with multiple pandas.Series, pandas.DataFrame,
              numpy.ndarray objects.
