Hello everyone,
I have a function F(x) = a * f1(x) + b * f2(x), where “a” and “b” are parameters and “f1(x)” and “f2(x)” are functions, which can hardly be expressed analytically, but it’s possible to evaluate these functions numerically for a set of argument values x = {x1,x2,x3,…} (e.g. for values, which correspond to the data points – data = {data1(x1), data2(x2), data3(x3),…}). How can I define (if it’s possible in principle) my pdf in this case?
Thanks a lot.
Maxim
