Hi, look at: P = { (W - K^2/3) / t + A [(W - K^2/3) / t]^3} E1 (t^4) / (25^2) K = P / (alfa D^0.5) this is a recursive definition. Is this what you want???? hope this helps, Daniel umby wrote: > Hi, > > > > I have some experimental data in the form of quadruplets {P, W, t, D}. > > How can I find the best fit parameters: alfa, A and E1 of the function: > > > > P = { (W - K^2/3) / t + A [(W - K^2/3) / t]^3} E1 (t^4) / (25^2) > > > > where K = P / (alfa D^0.5). > > > > Thank you > > -u > > >
