WebMSE = SSE n − p estimates σ 2, the variance of the errors. In the formula, n = sample size, p = number of β parameters in the model (including the intercept) and SSE = sum of squared errors. Notice that for simple linear regression p = 2. Thus, we get the formula for MSE that we introduced in the context of one predictor. WebUnexpectedly, adding more features to the NN models caused the MSE to somehow increase by 1.23%: although the difference was not significant, this confirmed the importance of careful feature engineering.
