Dropping outliers

[Steffie Kremer]

Hello,

I have an equation including the change in the futures rate and a dummy variable on days when there was an FOMC announcement (then the dummy is 1). Could somebody please tell me how I can drop outliers on the change in the futures rate (for example, changes in futures rates over 0.05), but that it drops it only when my dummy variable is equal to zero? (So there is no FOMC announcement?)

Thanks!

Use the smpl command. Something like

Code: Select all

smpl if @abs(futures)>.05 and dummy=0

Thank you for the tip!
The only thing is that if I use this equation, the large changes that are related to an FOMC announcement are also dropped, while these should not be dropped.
So I would like to drop all variables that satisfy the equation:futures >0.05 AND dummy=0. (so not futures>0.05 and dummy =1)

Thank you very much.
