I have some data where I have multiple conditions per subject (humans, in this case), who made repeated movements under these conditions. I’m interested in the variability of these movements. The data might look something like: subject_id cond1 cond2 x y 1 0 0 0.00, 0.01, …, 20.0 0.00, 0.7…

[image] janfreyberg: For example, the marginal variation is likely far higher in the middle of the movement, as the start was constrained and the movement was aimed at a fixed target. I don’t know if this is possible to model with a GP? Yes, you’d be doing what might be called a “heteroskedas…

Analysing repeated movement trajectories - is a GP the right approach?
