Quality analysis testing for quantifying reliability properties

Quality control generally requires data of higher quality to quantify the error in any measured quantity. The following work shows that the Proszyhski Reliability Criterion (PRC) is fulfilled if the measurement variance is greater than its prediction function based on the remaining observations. The partial derivatives with respect to the parameters of the residuals' equations are taking the role of the observations within the system. Therefore the prediction variance can be measured. If the prediction function is bounded then a reliable observational system (i.e. each observation has fulfilled the PRC) can be achieved.
