On the Power Performance of Test Statistics for the Generalized Rayleigh Interval Grouped Data

Abstract

In this paper, the weighted Kolmogrov-Smirnov, Cramer von-Miss and the Anderson Darling test statistics are considered as goodness of fit tests for the generalized Rayleigh interval grouped data. An extensive simulation process is conducted to evaluate their controlling of type 1 error and their power functions. Generally, the weighted Kolmogrov-Smirnov test statistics show a relatively better performance than both, the Cramer von-Miss and the Anderson Darling test statistics. For large sample values, the Anderson Darling test statistics cannot control type 1 error but for relatively small sample values it indicates a better performance than the Cramer von-Miss test statistics. Best selection of the test statistics and highlights for future studies are also explored.

“…Technology in the information age is constantly moving forward, and the application of information technology and information systems has brought many new or old challenges to the statistical work of electric power enterprises, which at the same time puts forward new requirements for the work of electric power statistics [1][2][3]. The information age is more concerned with how to discover information, interpret information, and collect information together to produce new information and knowledge [4][5].…”
