Greetings!

I have endpoints from a particle diffusion experiment that I would like to fit to a 2d gaussian function, returning the relevant parameters.

Also, given several of these particle diffusion experiments (several hundred particle endpoints), I would like to have some measure of whether the distributions are significantly different. Is there some sort of 2d KS test that I should use for this purpose?

Any help would be great.

Thanks!
