Advanced Methods in Biostatistics IV - Regression Modeling

Advanced Methods in Biostatistics IV covers topics in modern multivariate regression from estimation theoretic, likelihood-based, and Bayesian points of view. The course will cover extensions of these methods to correlated data using generalized estimating equations. The course will also cover more advanced topics for modern high-dimensional analysis, including sparse regression (Lasso), methods for higher order interactions (CART), and high-dimensional multiple testing.
