Matching is a statistical technique that evaluates the effect of a treatment by comparing the treated and the non-treated units in an observational study or quasi-experiment (i.e. when the treatment is not randomly assigned).
A type of research study that tests how well new medical approaches work in people. These studies test new methods of screening, prevention, diagnosis, or treatment of a disease. Also called a clinical trial. (NCI) A clinical trial is a research study to answer specific questions about vaccines or new therapies or new ways of using known ...
Radius matching: all matches within a particular radius are used -- and reused between treatment units. Kernel matching: same as radius matching, except control observations are weighted as a function of the distance between the treatment observation's propesnity score and control match propensity score. One example is the Epanechnikov kernel.
The information retrieval community has emphasized the use of test collections and benchmark tasks to measure topical relevance, starting with the Cranfield Experiments of the early 1960s and culminating in the TREC evaluations that continue to this day as the main evaluation framework for information retrieval research.
Peele states Project MATCH's failure to confirm a matching hypothesis [a] revealed oversights in their methods, as well as showing that American conceptions of alcoholism and treatment policy are fundamentally wrong. Research outside the United States has shown that subjective matching does work and other research shows that many with alcohol ...
Most of these are accompanied by a short description or definition, links to related descriptors, and a list of synonyms or very similar terms (known as entry terms). MeSH contains approximately 30,000 entries (as of 2022) and is updated annually to reflect changes in medicine and medical terminology. [3]

Fair random assignment (also called probabilistic one-sided matching) is a kind of a fair division problem. In an assignment problem (also called house-allocation problem or one-sided matching ), there are m objects and they have to be allocated among n agents, such that each agent receives at most one object.
