“…These scores are resampled with replacement according to the empirical distribution, generating the set 1s* , ..., 1n* and, afterwards, they should be smoothed, forming the set 1s* 1n* . Smoothening is the term attributed to the process of incorporating the properties of the original set of index scores into the resampled set, through the use of reflection methods (12,13), represented by the application of Eq. (4) to (6) set y 2i,s , ..., y 2p,n , which is normalized prior to computing the second set of index scores.…”
