Government surveys of business establishments receive a large volume of submissions where a small subset contain errors. Analysts need a fast-computing algorithm to flag this subset due to a short time window between collection and reporting. We offer a computationallyscalable optimization method based on non-parametric mixtures of hierarchical Dirichlet processes that allows discovery of multi...

Randomized response is a research method to get accurate answers to sensitive questions in structured sample survey. Simple random sampling is widely used in surveys of sensitive questions but hard to apply on large targeted populations. On the other side, more sophisticated sampling regimes and corresponding formulas are seldom employed to sensitive question surveys. In this work, we developed...

Scent stations usually are deployed in clusters to expedite data collection and increase the number of stations that can be operated for a given cost. Presumed benefits of cluster sampling may not be realized, however, unless cluster sizes are chosen with respect to sampling variation within and among clusters. To encourage and facilitate the use of efficient designs and reporting standards, we...

This report describes the results of an evaluation of random-digit-dialed sampling and telephone data collection procedures for the collection of health interview data from households. The study design included the following components: a comparison of data obtained by personal interview using area probability sampling with that obtained by telephone interview using random-digit-dialed sampling...

one of recent developments in modern societies is the evolution in the structure of power division in the family and changes in reciprocal actions between wife and husband. this research aims to study the factors affecting distribution of power in the family by using the theories of: social capital, valuable resources, and sociability of gender. the data has been collected through survey method...

The grouping of accessions into clusters is achieved by a classification strategy that partitions the original colWhen forming core subsets, accessions from a collection are classilection into groups with maximum distances between fied into clusters, and then samples are drawn from the clusters with accessions located in different groups and minimum disthe aim of maintaining the diversity of th...
