I was looking for a way to apply moving average filters to a time series.
To my understanding there isn't a built-in function in gretl, so I would
to know whether some user has already developed it.
If not, I think I will write a user function (I need it to show its
properties to my students).
In this case, I would like to know whether is available the convolution
function in gretl,
which is very helpful to combine filters. Any suggestion is obviously
Thanks a lot.
