I need just specific information.
I have a problem to solve.
I have 2 hyperbolic function
f1=1/(a+b*x+h*z) & f2=1/(c+d*x+l*z)
and I have 100 observations of x, z and y.
I want estimate the parameters a, b, h, c, d and l from data having
- if f1<=f2 and x<10 then y=f1 else y=f2
Can I fit this problem with JMSL nonlinearregression class?
Thanks for info

Look to your defns of f1 and f2. There is no functional difference.
