Hello!
I have recorded some data, and during the analysis I have noticed an interesting Nans values distribution. I measured the duration of Nans periods in gaze points, and checked the distributions of these periods. And this distribution has 3 picks.
The first pick around zero – makes sense, the short periods of just one or two values missing are the most common.
The second pick is around 100 missing gaze points in a row – these are blinks.
But then there is a third pick – around 300 missing gaze points in a row… And I don’t know what that is. I have checked for several people and it is the same for all of them.
Does anyone know what that could be?
Thank you very much in advance!
