Sorry, I am not on the gretl-devel list. I will join later.
>>>So does this mean that fcModels is the more general one and that HoltWinters is redundant?
No, they are not redundant. My fcModels.gfn could partially be thought to extend parts of Ignacio's HoltWinters despite I also wrote other forecasting models.
What Ignacio said, "...An important difference is that he (Yang) is looking for 'optimal' smoothing parameters", is just what I did in the fcModels.gfn. Why I included Ignacio's HoltWinters is just as what Ignacio said, "currently we don't have a way to call a function from a different package in the current gretl functions. So I just directly included the original script of Ignacio's.
Actually I would be very glad to see in the future that we would have such a way to call a function from a different package so that I don't have to rewrite the same functions with existing ones. Without this kind of "inclusion", it turned out the reason why fcModels.gfn has not updated HW2 with the ultimate versions of HoltWinters. (I personally apologize about this.)
Of course, it will be my pleasure to cooperate with Ignacio. But in fact, it was not my intention to write another version of Holt and Winters'. If Ignacio's package can be called, I will tend to call his existing ones.
>>>could you edit your package to make it English-only
Though I personally think currently 'English-only' is not very good for me to promote gretl in Taiwan as well as for Chinese users, I surely will conform to the decision of the gretl society. I support sven's idea that it is a clear example of how we need a way to translate function packages.
I agree to remove HW2 from my fcModels.gfn package and make it English-only but please allow me
to do this after ending of this semester since I will have an "online"
final exam in which fcModels.gfn has to be used by students.
Thanks for your great contributions.
