Hi Mayank,
That's correct. If the binSize is greater than 0, the answer is as you say.
It does say this in the documentation by the way:
Quote:Bin Size is the width of the moving average window, The deviation of value at the paricular point from the average of this window is the jitter.
If binsize=0, all frequencies are used to calculate the average.
If binsize=N, the last N frequencies are used to calculate the average.
Note, it is being updated to say "periods" rather than "frequencies" as it's a bit confusing otherwise.
The problem is that with binSize of 0, the answer is wrong, because of the mistake in the calculation of the overall mean period.
Regards,
Andrew.
