Statistical Matching and Official Statistics

Rivista di statistica ufficiale
Statistical matching procedures are methods that aim at the integration of sources. A description of real contexts in the Italian National Statistical Institute, in which these methods appear to be useful, is given. The necessary steps for the application of statistical matching are analysed.

A statistically-based ontology matching tool

Distributed and Parallel Databases, 2017
Ontologies have become a popular means of knowledge sharing and reuse. This has motivated development of large independent ontologies within the same or different domains with some overlapping information among them. In order to match such large ontologies, automatic matchers become an inevitable solution.

Statistical learning in official statistics: The case of statistical matching

Statistical Journal of the IAOS: Journal of the International Association for Official Statistics, 2019
Data integration is becoming a crucial task in National Statistical Institutes in order to exploit the information provided by already existing data sources. Here the focus is on statistical matching methods; they are designed to integrate data stemming out from traditional sample surveys referred to the same target population. In particular, this work

An Evaluation of Statistical Matching

Journal of Business & Economic Statistics, 1984
The validity of findings based on statistically matched data sets depends on the accuracy of underlying assumptions about relationships between variables that are unique to each input file. Simulations of statistical matching procedures on samples from populations with known characteristics provide the basis for an evaluation of the usefulness of ...

Matching Statistics to Graphs

1996
Sometimes it is reported that the average lawyer earns a lot of money; at the same time, the median income of lawyers is reported to be more modest. One year the average team in the National Football League made a sizable profit while the median team barely broke even. People often confuse the mean and the median of a distribution.

An investigation of statistical matching

Journal of Applied Statistics, 1988
This Paper examines the file-merging technique of statistical matching. Details are given of both its practical application and its numerical accuracy. In particular, it is shown that the ability of statistical matching to recreate correlations between variables existing only in different files is dependent on some respective assumptions which are ...

Using Statistics To Evaluate A History Match

Proceedings of Abu Dhabi International Petroleum Exhibition and Conference, 2002
Abstract Three methods are proposed for quickly evaluating the history match of a numerical simulation to actual reservoir performance. All of the methods rely on computing a set of deviation values, each of which is defined to be a calculated simulator result minus the corresponding surveillance measurement value. For any

Image statistics based on diffeomorphic matching

Tenth IEEE International Conference on Computer Vision (ICCV'05) Volume 1, 2005
We propose a new approach to deal with the first and second order statistics of a set of images. These statistics take into account the images characteristic deformations and their variations in intensity. The central algorithm is based on nonsupervised diffeomorphic image matching (without landmarks or human intervention). As they convey the notion of
