Splet31. dec. 2024 · Ordinary least squares is a method used by linear regression to get parameter estimates. This entails fitting a line so that the sum of the squared distance from each point to the regression line (residual) is minimized. Let’s visualize this in the diagram below where the red line is the regression line and the blue lines are the residuals. Splet16. nov. 2024 · Given a set of p predictor variables and a response variable, multiple linear regression uses a method known as least squares to minimize the sum of squared residuals (RSS):. RSS = Σ(y i – ŷ i) 2. where: Σ: A greek symbol that means sum; y i: The actual response value for the i th observation; ŷ i: The predicted response value based on …
