Renaming the question to better represent the intent.

| Mar 20, 2022 at 2:48 | comment | added | JoeBlackSci | @Henry Does that mean then that by fitting the polynomial regression, the model will include an erroneous bias. And that the transformation is more appropriate in this particular instance, but may not be for other datasets? | |
