Fitted line plot minitab

WebThe "fitted line plot" command provides not only the estimated regression function, but also a scatter plot of the data adorned with the estimated regression function. Minitab Procedure Select Stat >> Regression >> … WebSmaller values are better because it indicates that the observations are closer to the fitted line. The fitted line plot shown above is from my post where I use BMI to predict body fat percentage. S is 3.53399, which tells us that the average distance of the data points from the fitted line is about 3.5% body fat.

WebR2 is always between 0% and 100%. You can use a fitted line plot to graphically illustrate different R 2 values. The first plot illustrates a simple regression model that explains 85.5% of the variation in the response. The second plot illustrates a model that explains 22.6% of the variation in the response. WebThe fitted line is a regression line that examines the relationship between the probability of acceptances and the reference values of the measured parts. The general form of a fitted line is: Y = b 0 + b 1 X. Minitab regresses the z–score Φ -1 (Prob (Acceptance)) on reference values X T to get the intercept and slope.
