- Abstract
- There are many areas of applications where Gumbel distribution are employed such as environmental sciences and hydrology. The goodness-of-fit test for Gumbel distribution is very important in environmental sciences and hydrology data analysis. In most of the life testing experiments, the experimenter is often, unable to observe life time of all items put on test and the data available to the experimenter is censored data. Therefore, we propose the test statistics to test goodness of fit for the Gumbel distribution under progressive type II censoring using decile dispersion ratio. We compare the new test statistic with the Yun and Lee (2018) test in terms of the power of the test through by Monte Carlo method. As a result, the new test statistics are more powerful than Yun and Lee (2018) test. Also, we check the proposed test statistics using ball baring data.
