[ 1 ] - بازههای اطمینان برای نسبت و تفاضل دو شاخص C_pmk براساس روشهای مجانبی و خودگردانی پارامتری
Process capability indices are widely used in various industries as a statistical measure to assess how well a process meets a predetermined level of production tolerance. In this paper, we propose new confidence intervals for the ratio and difference of two Cpmk indices, based on the asymptotic and parametric bootstrap approaches. We compare the performance of our proposed methods with generaliz…
[ 2 ] - آزمون برابری ضرایب تغییرات در چند جامعه نرمال با روش خودگردانی پارامتری
The coefficient of variation is often used for comparing the dispersions of populations that have different measurement systems. In this study, the problem of testing the equality of coefficients of variation of several Normal populations is considered and a new test procedure based on Wald test and parametric bootstrap approach is developed. Since all the proposed tests for this problem are appr…
