[R] nonlinear curve fit of an implicit function

2010-10-05 Thread Schmitt, H. (Heike)
Hello, I want to perform a nonlinear curve fit in order to obtain parameter estimates from experimentally determined data (y in dependence of x), but with an implicit function, thus, a function of which I cannot isolate y on the left-hand side of the equation. As far as I understand, the function
