WebA fitted value is a statistical model’s prediction of the mean response value when you input the values of the predictors, factor levels, or components into the model. Suppose you have the following regression equation: y = 3X + 5. If you enter a value of 5 for the predictor, the fitted value is 20. Fitted values are also called predicted values. WebIn other words, the predicted mpg values are almost 65% close to the actual mpg values. And this is a good fit in this case. Step 5: Plotting the Relationship Between vehicle mpg and the displacement . We are going to use the plotnine library to generate a custom scatter plot with a regression line on it for mpg vs displacement values.
