| 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 |
