 2 Multicollinearity: Why does highly correlated columns in the design matrix lead to high variance of the regression coefficient? 1 Using the observation vector $\vec{y}$ instead of the centered observation vector $\vec{y_{d}}$ doesn't change the projection $\vec{\hat y}$ 1 Given domain and range of a monotone function, what is the maximum slope? 1 Proof of Correlation Coefficients 1 Multiple Regression with Categorical Predictor Variables of More than Two Levels
