We give some characterizations of the exponential distribution based on the distributional properties and the expected values of record values; the index of record values has the geometric distribution.

The private search problem is introduced, where a dataset comprised of L i.i.d. records is replicated across N non-colluding servers, each record takes values uniformly from an alphabet of size K, and a user wishes to search for all records that match a privately chosen value, without revealing any information about the chosen value to any individual server. The capacity of private search is th...

This paper shows that it is possible to create metrics for which re-identification is straightforward for situations in which continuous variables have been micro-aggregated one at a time using conventional methods. Introduction The purpose of this document is to provide overall justification on how micro-aggregation generally can yield public-use files in which re-identification rates are extr...

The effect of the length of record on the standardized precipitation index (SPI) calculation was investigated by examining correlation coefficients, the index of agreement, and the consistency of dry/wet event categories between SPI values derived from different precipitation record lengths. The effect was also illustrated by comparing SPI values derived from different lengths of record in some...

in this paper, we study the estimation problems for the two-parameter exponentiated gumbel distribution based on lower record values. an exact confidence interval and an exact joint confidence region for the parameters are constructed. a simulation study is conducted to study the performance of the proposed confidence interval and region. finally, a numerical example with real data set is given...

In the framework of disclosure control of a microdata set, an unique record is at risk of being identified. Even if a record is not unique in the microdata set, it may be considered risky if the frequency k of the cell, in which the record falls, is small. The notion of minimum unsafe combination introduced by Willenborg and de Waal (1996) is important in this respect. The purpose of this paper...

We characterize the exponential distribution in terms of the regression of a record value with two non-adjacent record values as covariates. We also study characterizations based on the regression of linear combinations of record values. AMS (2000) Subject Classification. 62G30, 62E10.
