Coefficient of Variation Based Goodness–of–Fit Tests for the Two–Parameter Weibull Distribution

Abstract

This article addresses Two-Parameter Weibull goodness-of-fit tests. First, tests based on the coefficient of variation of the log-transformed Weibull distribution are introduced. Then, the powers of the introduced tests are compared to empirical distribution-based tests, normalized spacing-based tests, and other types of tests. The results show that the simulated powers of the introduced tests compete well with the powers of previous tests.
