which differ from your weightcrosscheck. Here's the function he uses:

Yes, I was kind of expecting that my function is the odd one out.
However, the point is that we're talking about something where
supposedly the "last lag is zero" by construction, and apparently only
my naive implementation actually satisfies that. (Even for what we have
declared a "sane" case, theta1 \approx 1 and theta1 < theta2.)
So this leaves me even more puzzled than before.
