] | It is **almost always** a cheating to remove observations **to improve** a regression model. You should drop observations only when you truly think that these are in fact outliers.

* Pros: the model performance is better. The intuition is that, it is very hard to use ONE model to capture both "normal pattern" and "outlier pattern". So we remove outliers and say, we only build a model for "normal pattern".
* C... |

When I look at your model, it doesn't necessarily contain one large group and some outliers. In my opinion, it contains 1 medium-sized group (1 to -1) and then 6 smaller groups, each found between 2 whole numbers. You can pret... |
