Bayesian Analysis of an Optimal Five Period Cross-over Design

Cornelious Omwando Nyakundi & Isaac Kipkosgei Tum · Journal of Scientific Research and Reports · 2021

A crossover design is a repeated measurements design such that each experimental unit receives different treatments during the different time periods. In a majority of bioequivalence studies, design and analysis of cross-over using classical methods such as analysis of variance (...

Statistical Measure of Second Order Response Surface Rotatability Using an Infinite Class of Supplementary Difference Sets

Haron Mutai Ng’eno & Isaac Kipkosgei Tum · Asian Journal of Probability and Statistics · 2019

Rotatability is a desirable feature of a response surface experimental design. In case a design is non rotatable or exhibit surface of constant prediction variances that are nearly spherical then an attempt is made to make the design rotatable. In this paper, a measure of rotatab...
