Hey,

I am working on time series quarterly data which has the increasing trend. Before applying any technique, I have to detrend the data. So, my question is how to detrend my data through eviews software and in HP filter of eview the smoothing and cycle series we get what are these series and how it used in model? After detrending the data how we find the best technique to analyse the data?

Please suggest the sources like books, articles, research paper for these queries.
