Dataset Name:  NumAcc2

Description:   This is a constructed/fabricated data set
               to test accuracy in summary statistic calculations.
               The numbers are 2-digit floating point values and
               differ only in the last decimal place.
               Note--by construction, this data set has
                     sample mean                  =  1.2   (exact)
                     sample standard deviation    =  0.1   (exact)
                     sample autocorrelation coef. = -0.999 (exact)

Stat Category: Univariate
