I have a collection of samples (n ~ 20) that I have measured 2 isotopic values of and I want to calculate the likely % contribution of 4 source endmembers for each sample (eg sample 1 is 25% source 1, 12% source 2, 40% source 3, 23% source 4 +/- what ever; sample 2 is X% 1, Y% 2, Z% 3, A% 4, and so on). What package would you recoomend using? I am aware of Mixsiar, but I am not interested in the source decomposition of populations of samples; I want to know the breakdown on a sample by sample basis (within uncertainty of course)

Thank you

I'm tired of seeing the Harry Potter Audiobook ads in the app and wish to see different ones. How do I indicate I want different ads?

Thanks
