Create a model of car mileage as a function of weight, and simulate the response.
Create a quadratic model of car mileage as a function
of weight from the
load carsmall X = Weight; y = MPG; mdl = fitlm(X,y,'quadratic');
Create simulated responses to the data.
Xnew = X; ysim = random(mdl,Xnew);
Plot the original responses and the simulated responses to see how they differ.
