چکیده

This short paper provides a synthesis of the statistical disclosure limitation and computer science data privacy approaches to measuring the confidentiality protections provided by fully synthetic data. Since all elements of the data records in the release file derived from fully synthetic data are sampled from an appropriate probability distribution, they do not represent “real data,” but there is still a disclosure risk. In SDL this risk is summarized by the inferential disclosure probability. In privacy-protected database queries, this risk is measured by the differential privacy ratio. The two are closely related. This result (not new) is demonstrated and examples are provided from recent work. How protective are synthetic data? John M. Abowd and Lars Vilhuber School of Industrial and Labor Relations, Cornell University.

New Shewhart-type synthetic bar{X} control schemes for non-normal data

In this paper, Burr-type XII ̄X synthetic schemes are proposed as an alternative to the classical ̄X synthetic schemes when the assumption of normality fails to hold. First, the basic design of the Burr-type XII ̄X synthetic scheme is developed and its performance investigated using exact formulae. Secondly, the non-side-sensitive and side-sensitive Burr-type XII ̄X synthetic schemes are int...

Zooplankton and their protective effects on cardiovascular diseases

In the world-wide cardiovascular diseases are the most common. And mortallities are high. Many modifiable and non-modifiable risk factors for cardiovascular diseases have been identified. One of them is diets. In diet polyunsaturated fatty acids such omega-3 and omega-6 have protective effects on cardiovascular health. Polyunsaturated fatty acids are essentials for humans, have taken from foods...
