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)
Stat Category: Univariate: Summary Statistics
