Web$\begingroup$ Look, based on the mentioned example of sampled prediction and observed data values, the linear regression is established: Observation (O)= a + b X Prediction (P) (a, b are intercept and slope respectively). In this case, MSE = Σ(O-P)^2/n, where Σ(O-P)^2 is the Sum of Squared Erros (SSE) and n is the sample size. However, Mean Squared Residues … WebFor RSS, E (predicted Y - mean Y)2, we let df=k, since there are k independent variables in the regression model. We define the mean square, or the MSS (Mean sum of squares) for RSS and ESS as the sum of squares divided by the appropriate degrees of freedom. For reasons we'll see later, we do not compute this for TSS. Notice the "MSS for TSS ...
