HPfilter1s

[trubador]

This thread is about hpfilter1s add-in.

The add-in computes the one-sided version of well known Hodrick Prescott filter. In estimating the trend component, regular HP filter uses the full sample, which leads to end-point sensitivity. One-sided HP filter, however, only uses data available at given point in time. You can also use the add-in for trend forecasting purposes (just extend your sample and make sure that your workfile range allows it).

Hi,

Can you please post a sample command/programming reference for a case where lambda is set to 400,000?

Apologies, I hadn't seen the associated doc. It's really very helpful.

Thanks for the speedy reply.
