Normal linear model
μy = 2.5 + 1.5x σy = 0.8
The normal linear model on the previous page was for experimental data in which there were only a few x-values used. This diagram shows that a normal linear model specifies a normal distribution for the response at all x.
Drag the slider to show how the response distribution depends on x.
Click the y-x rotation button then take samples from the model. Depending on the pop-up menu, there can be repeated response values at four x-values, regularly spaced x-values, or random x-values for the data. Explain that the normal model covers all of these.
