The Commons Math NumAcc1.txt source code

File Name:     NumAcc1.dat

File Format:   ASCII
               Header          : lines  1 to 60       (= 60)
               Certified Values: lines 41 to 43       (=  3)
               Data            : lines 61 to 63       (=  3)

Dataset Name:  NumAcc1

Description:   This is a constructed/fabricated data set
               to test accuracy in summary statistic calculations.
               The numbers are large (8-digit integers) and
               differ only in the last decimal place.
               Note--by construction, this data set has
                     sample mean                  = 10000002 (exact)
                     sample standard deviation    =        1 (exact)
                     sample autocorrelation coef. =     -0.5 (exact)
