The modified Allan variance (MVAR), [2] also known as mod σ y 2 (τ), is a variable bandwidth modified variant of Allan variance, a measurement of frequency stability in clocks, oscillators and amplifiers. Its main advantage relative to Allan variance is its ability to separate white phase noise from flicker phase noise.
The Wisconsin Card Sorting Test (WCST) is a neuropsychological test of set-shifting, which is the capability to show flexibility when exposed to changes in reinforcement. [ 1 ] [ 2 ] The WCST was written by David A. Grant and Esta A. Berg.

In statistics, the Cochran–Mantel–Haenszel test (CMH) is a test used in the analysis of stratified or matched categorical data. It allows an investigator to test the association between a binary predictor or treatment and a binary outcome such as case or control status while taking into account the stratification. [ 1 ]
The test has since been translated into Italian, [5] Chinese, [1] and French. [6] The scores of the scale have reported good reliability and validity across multiple study samples. [1] In a study conducted by Chinese researchers in 2009, the Modified Overt Aggression Scale was found to be both reliable and valid. [1]
