Re: [Gretl-devel] Midas syntax, small issue

I don't want to open too many Midas threads, so I'm kind of hijacking my own: Here's another issue, but this time it looks like a bug to me. From what I understand, the polynomial specification beta-zero-last-lag (type code 2) should give a coefficient weight of zero for the last lag, hence its name. (The only exception should be the case when the two hyperparameters are both one, theta = {1, 1}.) However, consider these examples: <hansl> eval mweights(10, {0,0}, 2)' # gives 0.5 at the end eval mweights(10, {0.5, 0.5}, 2)' # dito eval mweights(10, {1.1, 1}, 2)' # gives 0.1194 eval mweights(10, {2, 1}, 2)' # gives 0.2 </hansl> Am I missing something? If it's really a bug, does it only affect the mweights() function or does it spill over into actual midasreg results? This is with an August snapshot. Thanks, sven
