I have x, y data (pollen and seed dispersal from oaks !) that I would like to fit with a function which look like this:
p(a,b,x,y)=b/(2*pi*a�gamma(2/b))*exp(-(square_root(x�+y�)/a)power(b))
I am looking for a and b values that fit my data at best. Can someone give me hints to perform such an analysis with R ?
Thanks a lot
Sophie
