The main purpose of matching is to improve statistical efficiency (precision).Click to see full answer. Also question is, what is the purpose of matching in case control studies?Matched case-control study designs are commonly implemented in the field of public health. While matching is intended to eliminate confounding, the main potential benefit of matching in case-control studies is a gain in efficiency. what is a matched analysis? From Wikipedia, the free encyclopedia. Matching is a statistical technique which is used to evaluate 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). Keeping this in view, why do you match? In practice, the matching principle combines accrual accounting (wherein revenues and expenses are recorded as they are incurred, no matter when cash is received) with the revenue recognition principle (which states that revenues should be recognised when they are earned or realised, no matter when cash is received).What is age matched control?Age and sex matching of controls means a similar proportion to the cases fall into the various categories defined by the matching variable (sex and age in this study). For instance, if 25% of the cases are males aged 65-75 years, 25% of the controls would be taken to have similar characteristics.
