Nettet14. des. 2024 · The Hodrick-Prescott Filter is a smoothing method that is widely used among macroeconomists to obtain a smooth estimate of the long-term trend component of a series. The method was first used in a working paper (circulated in the early 1980’s and published in 1997) by Hodrick and Prescott to analyze postwar U.S. business cycles. Nettet2 dager siden · Here's why.

NettetThe equation you are looking for is. λ α = 1 α 4 λ 1. which is the adjustment factor derived by Ravn and Uhlig (2002). They derived the smoothing factor for annual data with this formula using the λ = 1600 for monthly data which was originally suggested by Hodrick and Prescott. That is. λ annual = 1 4 4 1600 = 6.25.
