Re: [Gretl-users] Scaled Frequency in Periodogram
Yes, that seems to be what Gretl is doing. Thanks. The next question is
why? What is the advantage of scaling the frequency in this way?

I don't have this reference, but looking at the numbers I can guess that:
if T is the period, and Nobs the number of observations, the scaled frequency
is
f=Nobs/T,
or said in another way, if w is the angular frequency, (w=2*pi/T)
f=w*(Nobs/2*pi)
