, -the probability of the null being true
-observed level of significance

occurs as "before and after"
Cyclical Component

systematic pattern in the long term where periods are at least a year or
more
What does Cooks Distance measure?
Give this one a try later!
-measures leverage and residuals to determine if an outlier is present
-higher the leverage and residuals, higher the Cooks D
-if a Cooks D > 4/n then it is influential
