Computes efficiency scores for the given DMUs (alternatives) using SMAA-D method and CCR Data Envelopment Analysis Model with hierarchical structure of outputs. For given number of buckets and samples, returns a matrix with alternatives in each row and buckets representing efficiency intervals in each column. Single cell indicates how many samples gave efficiency scores of respective alternative in respective bucket.
(For outputs, see below)
A list of alternatives (DMUs).
