Dr. Swearingen earned his PhD in Biostatistics from the Medical University of South Carolina. His statistical research interests have developed in large part due the challenges encountered in prior collaborative projects in which the outcome of interest defied standard analytical techniques due to a large proportion of zero measurements. This problem of extreme values skewing an outcome's distribution is a ubiquitous one and often renders the usage of canonical analysis questionable. Research into advanced methods, including Dr. Swearingen’s work on Beta Regression as one possible method of analyzing these data, is of importance and great significance.
