In this paper, we present a new and reasonable measure of privacy protection of randomized response with or without allowing for the auxiliary variable and compare the unrelated question model, the addition model, the multiplication model, the optional randomization model, the generalized multiplicative model and the forced model in the light of the efficiency and protection privacy.

In sample surveys, it is usual to make use of auxiliary information to increase the precision of estimators. We propose a new chain ratio estimator of a finite population mean using two auxiliary variables and obtain mean square error (MSE) equations for proposed estimator. We find theoretical conditions that make proposed estimator more efficient than estimator of Abu-Dayyeh etc using two auxiliary...
We propose some ratio estimators of a finite population mean using auxiliary variable and obtain mean square error (MSE) equations for all proposed estimators. We find theoretical conditions that make each proposed estimator more efficient than the traditional ratio estimators. In addition, we support these theoretical results with the aid of a numerical example.
Web search engines work well for finding crawlable pages, but not for finding datasets hidden behind Web search forms. On this deep Web, many sources are structured by providing structured query interfaces and results. Organizing such structured sources into a domain hierarchy that users can browse to find these valuable resources and is one of the critical steps toward the large-scale integration...
