Theiler window

[Marina]

Hello,
I am not sure I understand what the Theiler Window means in practical terms. I'll explain what I think it means and my question using an example.
(A sketch is appended)
We have a time series with measurements every hour (24 measurements every day) and it has a daily seasonality. I estimate the embedding dimension, delay etc., etc. …
Let say, the system is in a state X at 15:00 April, 4 and I take a Theiler Window of 6 gaps, so the first time the system could reach the state X would be 21:00 April, 4.
Now, let's imagine the system actually recurs to the state X on April, 5 at 12:00, 13:00, 14:00 (because the periodicity is not perfect and because of the tangential movement). The next Theiler Window will encompass the times 13:00,14:00, 15:00, 16:00 and 17:00, being 18:00 the first allowed time for a possible recurrence of the state X.
By the way, if I have a time series which is partially periodic but also partially laminar, I think the Theiler Window would remove the laminarity, so maybe I shouldn’t use it.
Thanks in advance,
Marina

Hi Marina,

the Theiler window corrects only the recurrences that are close to the reference point. All other, "futher away" points are not corrected. For a RP it means that the Theiler window is a small band along the main diagonal.
Therefore, it will only partly affect the LAM measure.
