WebYou put a semicolon (;), you type the value of the smoothing parameter usually referred to as lambda (for quarterly data, this parameter is usually set to 1600, and for annual data to 100), and finally you put an end-bracket so that now you have in the formula field: =HP (D4:D112;1600) It is now tempting to hit "Enter", but do not do that!

WebThey 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 You can re-arrange the equation and then solve the optimal smoothing factor for any data frequency. You can get the monthly smoothing factor from
WebI am not very familiar with filters. The Hodrick-Prescott filter as one can find it e.g. in wikipedia is two-sided. I also found an R implementation for this in the R package mFilter.There the filter is given as: find $(\tau_t)_{t=1}^T$ such that $$ \left(\sum_{t=1}^T (y_t - \tau_t)^2 + \lambda \sum_{t=2}^{T-1} (\tau_{t+1}-2 \tau_{t} + \tau_{t-1} )^2\right) …
