WebFrom this, the model can make predictions about test data. Evidence of the [simple] wikipedia formula being wrong is that it produces negative r_squared values, which means it's coming up with the wrong slope for the best fit line for non-trivial data. Luckily, polynomial regression allows for the accurate modeling of non-linear relationships.
