Hello,

In part e), after fitting the model we chose, we noticed 4 observations outliers + leverage points, so we decided to remove them. But after refitting the model without thoses observations a new outlier + leverage point observation appears.

Is that normal ? If so, should we refit the model again without that observations ?

Thanks in advance,

Jérémy
