Linearity test definition
NettetWhenever we create a test to screen for a disease, to detect an abnormality or to measure a physiological parameter such as blood pressure (BP), we must determine how valid that test is—does it measure what it sets out to measure accurately? There are lots of factors that combine to describe how valid a test is: sensitivity and specificity are two such … http://www.spsstests.com/2015/03/step-by-step-to-test-linearity-using.html

In mathematics, a linear map or linear function f(x) is a function that satisfies the two properties: • Additivity: f(x + y) = f(x) + f(y). • Homogeneity of degree 1: f(αx) = α f(x) for all α. These properties are known as the superposition principle. In this definition, x …
