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)
|
|
|
