On the Difference in Cycling Pattern on Linear and Higher-Order Effect Designs

Okim I. Ikpan & Felix N. Nwobi · Asian Journal of Probability and Statistics · 2023

D-optimality is a design criterion that seeks to maximize the determinant of the information matrix, or equivalently minimize the determinant of the inverse information matrix of the design. This design criterion results in maximizing the differential Shannon information content...

John E. Usen, Okim I. Ikpan, Mfawa D. Santos, Anthony A. Isaac, George C. MacGeorge & Mmekutufon F. Ekpety · Asian Journal of Probability and Statistics · 2021

In some production and administrative processes, the occurrence of certain events is best described by a hyper-geometric distribution, which in turn should be pictorially depicted by what should be called a “hyper-geometric chart (Hg-chart)” in the field of Statistical Quality Co...
