Peng Zhou

MA is one way of detrending. In macro data, one of the most popular detrending technique is HP-filter, which is actually an optimal MA.

Salah L. Zubaidi

Dear Peng

Can use this method for daily data ?

Yes, of course, you only have to adjust the parameter of lambda. Try google.

Gökhan Cebiroğlu

MA is rather a way of de-noising your data. It can still have a trend.

Gokhan, HP filter guarantees that the filtered data has no trend. But you are right in general. After a simple MA, you may still have trend.

Dear Both,

Thank you very much
