Dear netters I am a chemist ( another excuse to be poor in mathematics :) ) , I need to fit some experimental data to a mathematical model , the model contains 4 or more independant variables and has the following form : f(x,y,z,p)= a1 * x**b1 + a2 * y**b2 + a3 * z**b3 + a4 * p**b4 I need to optimize the ai's and bi's to fit the experimental points f. I have tried the function 'Fit' in mathematica but it can only optimize the ai's and not the bi's. I would appreciate any help i can get.
