Security: Accessibility, security, and accuracy in statistical...

In pvrank: Rank Correlations

Description

Effectiveness of security mechanisms for protecting numerical databases.

Usage

data(Security)

Format

A data frame with 40 observations on the following three variables.

OV

Original values.

AP

Additively perturbed.

MP

Multiplicatively perturbed.

Details

The data set include a "true" series of values drawn from a lognormal population, sorted in ascending order. Data are perturbed by using the MP and the additive AP methods together with the relative position of the perturbed value.
