Re: [Gretl-devel] Hodrick-Prescott parameter

But with respect to a longer discussion of HP in the guide I'm not so sure, this could get quite fundamental. For example, here are some other recent interesting (and critical) papers: - Phillips, Peter C.B., and Sainan Jin. 2015. “Business Cycles, Trend Elimination, and the HP Filter,” Cowles Foundation Discussion Paper No. 2005, Yale University. - James D. Hamilton 2016. "Why You Should Never Use the Hodrick-Prescott Filter", http://econweb.ucsd.edu/~jhamilto/hp.pdf But I'm not at all against "aligning" the default smoothing values based on some common criterion (where the criterion value would be arbitrary I guess and would simply imply the convention of 1440 for quarterly data). cheers, sven
