            3.2 Enhanced Scatter Search – Composite I-distance indicator (eSS-CIDI)
                approach
                To scrutinize the weighting scheme of the SSI and potentially to reduce
            the number of indicators which are used in its computation we propose the
            recently devised enhanced Scatter Search  – Composite I-distance Indicator
            (eSS-CIDI) approach (Maricic, 2018). The idea of the approach is to obtain a
            data-driven weighting scheme which will produce the most stable rankings of
            entities if the sensitivity analysis is conducted for the weighting scheme. The
            stability  of  the  ranks  is  measured  using  standard  deviations  of  relative
            contributions (Dobrota et al., 2016; Murias et al., 2008). Relative contribution

                           
              , e e 1,2,...,n  is  the  percentual  share  of  the  weighted  indicator  in  the
            overall  composite  index.  Therefore,  if  the  contribution  of  indicator  i  of  all
            observed entities varies that indicates that the stability of the results and ranks
            is  low  (Dobrota  et  al., 2016;  Savic  et al.,  2016). Accordingly,  the  goal  is  to
            propose  a  weighting  scheme  which  will  minimize  the  sum  of  standard
            deviations  of  relative  contributions  of  all  indicators  which  are  used  in  the
            framework.
                The eSS-CIDI approach is conducted in three steps. The first step is to
            conduct the bootstrap CIDI to devise bounds within which the novel weighting
            scheme will be chosen from. The bootstrap CIDI has already been used  to
            restrain GAR DEA model (Data Envelopment Analysis) (Radojicic et al., 2018).
            The bootstrap CIDI consists of performing the Composite I-distance Method
            (CIDI) on m out of n samples without replacement where m is the subsample
            size  and  n  is  the  sample  size.  Namely,  after  each  iteration,  a  novel  CIDI
            weighting scheme will be obtained. As the subsample size we chose 0.632 n
