Hi,

(hope this is the right forum to ask)

suppose I have a 2D scatter plot plotting some correlation between two variables.

Suppose that due to some underlying processes the plot shows a structure having,

say, two set of points/clusters (maybe overlapping) with different correlation coefficient.

Is there some multivariate tool in ROOT/RooFit/etc with which one can recognize such a pattern

in a 2D histo/image and sort the points (perhaps in some probabilistic way) automatically according to which correlation they correspond to?

Or is there some method name you could suggest what one may try to search for in the literature?

Thanks for any ideas,

Balint
