Popis: | Using exact and asymptotic distributions, formulas were developed to derive population variances and uncertainties, and their corresponding unbiased estimates, for the method performance statistics, i.e., the sample mean (y_bar..), the repeatability variance and standard deviation and (sr2 and sr), and the reproducibility variance and standard deviation (sR2 and sR) and obtained from collaborative study of an analytical method. |
