We show that one should not use the one-sided Hodrick-Prescott filter (HP-1s) as the real-time version of the two-sided Hodrick-Prescott filter (HP-2s): First, in terms of the extracted cyclical component, HP-1s fails to remove low-frequency fluctuations to the same extent as HP-2s.

The Hodrick–Prescott filter (also known as Hodrick–Prescott decomposition) is a mathematical tool used in macroeconomics, especially in real business cycle theory, to remove the cyclical component of a time series from raw data. It is used to obtain a smoothed-curve representation of a time series, one that is more … See more The reasoning for the methodology uses ideas related to the decomposition of time series. Let $${\displaystyle y_{t}\,}$$ for $${\displaystyle t=1,2,...,T\,}$$ denote the logarithms of a time series variable. The series See more • Enders, Walter (2010).

WebThe filter identifies the components τ t and c t by minimizing the objective function. ∑ t = 1 T c t 2 + λ ∑ t = 2 T-1 ((τ t + 1-τ t)-(τ t-τ t-1)) 2, where T is the sample size of y t and λ is a tunable smoothing parameter. The first term minimizes the deviation of the cyclical component c t = y t-τ t from the overall series data.
