NumAcc2: NumAcc2 NIST Univariate Data Set.

In ab9sq/Rqualification: A series of function to test R against NIST data sets

Description

Dataset of 1001 2-digit points

Usage

NumAcc2

Format

101 observation of 1 variable:

Details

This generated/fabricated dataset consists of 1001 2-digit floating-point values: a single 1.2, followed by 500 pairings of 1.1 and 1.3. By construction, this data set has sample mean = 1.2 (exact); sample standard deviation = 0.1 (exact); and sample autocorrelation coef. = -0.999 (exact). The construction was carried out based on considerations described by Simon, Stephen D. and Lesage, James P. (1989): Assessing the Accuracy of ANOVA Caluclations in Statistical Software", Computational Statistics \& data Analysis, 8, pp. 325-332.
