In this paper, the topic of student evaluation of instruction has been addressed with a new approach. Student behavior in reporting on evaluation instruments was analyzed using a model based on utility and opportunity cost. This model carried a set of hypotheses that represent a large group of...

This paper is based on the application of a Bayesian model to a clinical trial study to determine a more effective treatment to lower mortality rates and consequently to increase survival times among patients with lung cancer. In this study, Qian <italic>et al.</italic> [13] strived to determine if a Weibull...

In this paper, we introduce a new nonparametric test of symmetry based on the empirical overlap coefficient using kernel density estimation. Our investigation reveals that the new test is more powerful than the runs test of symmetry proposed by McWilliams [31]. Intensive simulation is conducted...

We provide several methods to compare two Gaussian distributed means in the two sample location problems under the assumption of partially dependent observations. Simulation studies indicate that our test procedure is frequently more powerful than other methods depending on the ratio of the...
