Statistical concepts of capability of detection

摘要

The minimum detectable value of a measurement system is the smallest true value of the measurand AT that can be detected as distinct from the true value x = 0 with a specified probability 1-β If the measurand X is measured indirectly and the directly measurable variable Y is linearly related to X, the minimum detectable value depends on the design of the measurement system, i.e. the calibration experiment for the estimation of the linear relationship and the number of repeated measurements of the sample. In this paper a design is derived that assures the minimum detectable value to be equal to a specified value.
