Keith E Muller, Ph.D.
Professor
About Keith E Muller
Professor Muller has external research funding from a variety of federal and state agencies. His more than 150 peer-reviewed journal publications are split roughly equally between scientific collaborations and biostatistical methodology developments. In addition, Professor Muller is the first author of two books on the theory and practice of linear models. He is a fellow of the American Statistical Association.
With funding from a series of NIH grants, Professor Muller serves as co-principal investigator in collaboration with Dr. D. H. Glueck (University of Colorado Denver Medical School) for the development of GLIMMPSE software and the website SampleSizeShop.org. The site includes a free online short course on design, power and sample size for studies with multilevel (clustering) and longitudinal dimensions. The site also includes free and open-source software, GLIMMPSE, that requires only a web browser to compute power and sample size for multilevel and longitudinal designs.
