For linear regression,the value of SSᵣₑsᵢdᵤₐl can be computed directly by Σ(Y -Ŷ)².

Question

Quizplus · Accepted Answer

SSᵣₑsᵢdᵤₐl represents the sum of square of residuals or errors in the linear regression model. Residuals are the difference between the actual observed values (Y) and the predicted values (Ŷ) by the linear regression model. Therefore, the direct formula to calculate SSᵣₑsᵢdᵤₐl is Σ(Y -Ŷ)².
