Linear Models - UCCS. Applies linear algebra to statistics. Appears to use textbook "Intro to Linear Regression Analysis" Montgomery et al 3rd edition/. To quote the site "Methods and results of linear algebra are developed to formulate and study a fundamental and widely applied area of statistics. Topics include generalized inverses, multivariate normal distribution and the general linear model. Applications focus on model building, design models, and computing methods. The Statistical Analysis System (software) is introduced as a tool for doing computations." see this course page
