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 sensitive to long-term than to short-term fluctuations. 2. The HP Filter has two objectives, with the importance of each objective denoted by the user given value of lambda: Objective 1: minimize the τt τ t in the term in the square brackets such that we minimize the changes in the estimated growth rate over time. Objective 2: We want to bring the τt τ t to be as close as possible to yt y t to The parameter lambda for HP-filter is computed for different interval prediction. The Hodrick-Prescott filter, also known as the HP filter or Hodrick-Prescott decomposition, was proposed by Hodrick and Prescott (1997). It is a scientific tool used for time series decomposition, specifically for separating the trend and cycle components from Use Hodrick-Prescott filter for variables y1, y2, and y3 to obtain cyclical components with prefix cycl Statistics >Time series >Filters for cyclical components >Hodrick-Prescott 1. 2tsfilter hp— Hodrick-Prescott time-series filter Syntax Filter one variable tsfilter hp type newvar = varname if in, options Filter multiple I'm applying the HP filter to time series data to remove the cyclical component of a time series (TS) from raw data.
