MATLAB: Calculating Residual Values in a Regression

regressionresidual values

I have a doubt in calculating Residual values for a given regression model. Consider this case (first table with x and y values). As we know that residual values are (y-y_hat), I calculated them using the same formula and the values i got are same as mentioned in the website i linked. But, when i try to find the residuals using fitlm/LinearModel.fit methods, I get different values. please see the code and help me where I'm wrong.
    y=[70 65 70 95 85]';
    x=[60 70 80 85 95]';
    mdl=LinearModel.fit(y,x);
    disp(mdl.Residuals.('Raw'))
The Output I'm getting for the above code is,
-12.7778
  0.9524
  7.2222
 -6.4286
 11.0317
which doesn't match with the residuals given in the website
   4.5890
  -6.8493
  -8.2877
  13.4932
  -2.9452

Best Answer

In MATLAB's linearmodel.fit command, x is the first parameter and y is the second. You have them reversed.
