Let’s proceed to the regression putting not_hsg, hsg, some_col, col_grad, and avg_ed as predictors of api00. Go to Linear … WebThe next table shows the multiple linear regression model summary and overall fit statistics. We find that the adjusted R² of our model is .398 with the R² = .407. This means that the linear regression explains 40.7% of the variance in the data. The Durbin-Watson d = 2.074, which is between the two critical values of 1.5 < d < 2.5.
