Statistics and Probability

Statistics research at the Department focuses on the broad areas of simultaneous inference, analysis of non-Euclidean data, analysis of categorical data, Bayesian modeling, object-oriented data analysis, spatial data analysis, and inference under dynamic parametric models. These include more specific areas of interest such as control and estimation of the false discovery rate, statistical modeling of data on the sphere, statistical analysis of trees, images, and functional data, empirical studies of machine learning models, and change-point analysis under fixed dimensions as well as high dimensions. Statistics faculty members at the Department often conduct research in collaboration within the Department and with the School of Food Science, Department of Pharmaceutical Sciences, School of Materials Sciences and Mechanical Engineering, College of Veterinary Medicine, Department of Engineering and Computer Science, and Department of Management, Information systems, and Entrepreneurship.
