Introduction to Linear Regression
Relationships & Predictions
P1 The Statistical Learning Framework
Statistical learning = a set of approaches for estimating that relationship
Parametric Approach: Linear Regression
The assumption: Relationship between X and Y is linear
Y≈β0+β1X1+β2X2+…+βpXp
The task: Estimate the β coefficients using our sample data
The method: Ordinary Least Squares (OLS)
P2 Two Different Goals
Prediction vs Inference
