Note: Although the model based on y = β0 + β1x + β2x2 is not linear
... is not linear in x, it is linear in the parameters. Because of this, we still term this a linear model. It is this fact that makes the least-squares solutions easy to find. This model is no more difficult to fit than the model y = β0 + β1 ...
