Topics related to spatial statistics include the analysis of spatial point patterns, Gaussian processes with spatial correlation functions and prediction/kriging, and spatial autoregressive models. A primary goal is for learners to recognize settings when standard statistical methods based on assumptions of independence are inappropriate. In addition, learners will gain awareness of and experience in applying modern statistical methods for the analysis of dependent data. Applications in areas ranging from finance to ecology to public health will be emphasized.

While much of statistics and data sciences is framed around problems of prediction, Design Principles and Causal Inference for Data-Based Decision Making will cover basic concepts of statistical methods for inferring causal relationships from data, with a perspective rooted in a potential-outcomes framework. Issues such as randomized trials, observational studies, confounding, selection bias, and internal/external validity will be covered in the context of standard and non-typical data structures. The overall goal of the course is to train learners on how to formally frame questions of causal inference, give an overview of basic methodological tools to answer such questions and, importantly, provide a framework for interrogating the causal validity of relationships learned from data. The target audience for this course is someone with basic statistical skills who seeks training on how to use data to characterize the consequences of well-defined actions or decisions.
