Something like
Minimize[Simplify[
Total[(y - (a + b (Exp[40*(x + c*y)/d] - 1) - (x + c*y)/e))^2 /.
Thread[{x, y} -> #] & /@ data]], {a, b, c, d, e}]

Hi,
I have data in (x,y) pairs. I have an equation:
y= a +b (Exp[40*(x + c*y)/d] - 1) - (x +c*y)/e
where a,b,c,d, and e are fitting parameters.
Note that this equationcannot be put in the form y=f(x).
How do I fit this equation to my x,y data?
Thanks,
Michael
