Microdata Protection
Governmental, public, and private organizations are more and more frequently required to make data available for external release in a selective and secure fashion. Most data are today released in the form of microdata, reporting information on individual respondents. The protection of microdata against improper disclosure is therefore an issue that has become increasingly important and will co...

0 1 2 3 as does its derivative 0 (): 0 0 1 0 2 0 3 0 0 = 0 01 0 02 0 03 0 04 = 0 See Tables 1 & 2 for the cases = 0 1 2 and Tables 3 & 4 for the cases = 12 32 52. These appear in many physical applications that we cannot hope to survey in entirety. We will state only a few properties and several importan...
متن کاملFat Fisher Zeroes
We show that it is possible to determine the locus of Fisher zeroes in the thermodynamic limit for the Ising model on planar (“fat”) φ random graphs and their dual quadrangulations by matching up the real part of the high and low temperature branches of the expression for the free energy. The form of this expression for the free energy also means that series expansion results for the zeroes may...
متن کاملThin Fisher Zeroes
Biskup et al. [Phys. Rev. Lett. 84 (2000) 4794] have recently suggested that the loci of partition function zeroes can profitably be regarded as phase boundaries in the complex temperature or field planes. We obtain the Fisher zeroes for Ising and Potts models on non-planar (“thin”) regular random graphs using this approach, and note that the locus of Fisher zeroes on a Bethe lattice is identic...
متن کاملAggregate behavior and microdata
It is shown how one can effectively use microdata in modelling the change over time in an aggregate (e.g. mean consumption expenditure) of a large and heterogeneous population. The starting point of our aggregation analysis is a specification of explanatory variables on the micro-level. Typically, some of these explanatory variables are observable and others are unobservable. Based on certain h...
