Mostra el registre d'ítem simple A test for normality based on the empirical distribution function dc. A test for normality based on the empirical distribution function.

Critical values are normaoity via Monte Carlo for several sample sizes and different significance levels. We study and compare the power of forty selected normality tests for a wide collection of alternative what is normality test in research. From the simulation study results it is concluded that the best performance against asymmetric alternatives with support on the whole real line and alternative distributions with support on the positive real line is achieved by the new test.

Other findings derivedfrom the simulation study are that SJ and Robust Jarque-Bera tests are the most powerful ones for symmetric alternatives with support on the whole real line, whereas entropy-based tests are preferable what is normality test in research alternatives with support on the unit interval. Nom: Cerca a UPCommons. Torabi, H. In this paper, a goodness-of-fit test for normality based on the comparison of the theoretical and empirical distributions is proposed.
