Peak at block length v.s. on-the-fly method
Posted: Sat Aug 27, 2016 1:15 pm
Dear,
I have a question about reblocking analysis.
Data below seems to be converged at 131072
block length (peak of Std.Err.), but
on-the-fly says, on the other hand, the optimal
block length is 4096.
Which one should I trust?
