Reply To: data breakdown bestLag

Hi gr220,

“w” is the abbreviation for “window”, i.e. w1=window1; w2=window2
w2 –2.56 may be interpreted as follows:
In your window number “2”, the lag with the highest cross-correlation-coefficient was “–2.56 seconds”
bestLag thus means the time-delay (lag) where the association between the two time-series was at it’s highest value.

grand average is the mean ccf for all lags and all windows. It may be described as the “overall synchrony” in this specific interaction.

You can find a fully detailed description of all parameters in the following publication:

Cheers, Fabian
