Validation experiment for using random values

This file aims to validate if the assumption of using random values to replace the values of irrelevant elements is feasible. The sheet 'Results of Relative Errors' presents te results of relative errors caused by different sets of random values. The other sheets show how the RAS method work for an I-O case with 19 industries. We can simply generate a new set X1' of random values by double clicking any cell in Excel.
