          Parameters
          ----------
          comparison_vectors : pandas.DataFrame
              The comparison vectors.
          match_index : pandas.MultiIndex
              The true matches.
          return_type : str
              Deprecated. Use recordlinkage.options instead. Use the option
              `recordlinkage.set_option('classification.return_type', 'index')`
              instead.
  
          Returns
          -------
          pandas.Series
              A pandas Series with the labels 1 (for the matches) and 0 (for the
              non-matches).
