RT Journal Article SR Electronic A1 Rogowski, Andrzej T1 Comments on the Power of Kolmogorov Test JF Communications - Scientific Letters of the University of Zilina YR 2013 VO 15 IS 3 SP 89 OP 95 DO 10.26552/com.C.2013.3.89-95 UL https://komunikacie.uniza.sk/artkey/csl-201303-0015.php AB This paper presents the results of estimating the power of Kolmogorov test and its modifications for testing hypothesis about an exponential distribution against the alternative hypothesis (population has a Weibull distribution). The power of test was calculated based on a distribution of empirical cumulative distribution function and limiting distribution, as well as computer-simulation methods. Some important properties and limitations were given that are related to power simulation study of goodness-of-fit tests.
