In this study, we propose a standardized likelihood ratio test for homogeneity of variances of several normal populations. We obtain the exact mean and variance of the likelihood ratio test. The proposed test, which does not require intensive simulat

Publikováno v: Iranian Journal of Science and Technology, Transactions A: Science. 43:1705-1711

We propose standardized log-likelihood ratio test which is not based on any resampling methods and intensive computer method for the equality of inverse Gaussian scale parameters. Thus, in practice the proposed test is much easier to implement, espec

The inventory model of type (s, S) is one of the most common used inventory models used in many problems of stock control. It is very important to know statistical characteristics such as the moments of the inventory model of type (s, S). However, si

A new computational approach test for one-way ANOVA under heteroscedasticity

Autor: Hasan Hüseyin Gül, Esra Gökpinar, Gamze Guven, Hakan Tahiri Mutlu, Fikri Gökpinar

This paper proposes a new test statistic based on the computational approach test (CAT) for one-way analysis of variance (ANOVA) under heteroscedasticity. The proposed test was compared with other popular tests according to type I error and power of
