Hello, I'm new user of Mathemetica. I'm trying to fit data to a model, that is defined by an integral, using NonlinearModelFit. The integral contains the parameter I'm looking for. When I set a particular value for the parameter, NIntegrate works well giving an estimate of the integral value; but when I define the model within the fitting algorithm, the integral cannot be numerically evaluated since it contains the non-numerical parameter giving the "inumr" error message. Do anyone know how to fit data with model parameters contained in an integral that must be numerically evaluated?
