I have a set of data that I would like to fit to an equation using the following initial equation: x[[n+1] = A x[[n]] ( 1 - B X[[n]]) This is a typical nonlinear, dynamical equation used in many texts as a function that may interate equations to chaotic states. Several people have suggested I use NonlinearFit in the Nonlinear package. I haven't any clue how to set up this for NonlinearFit. I know I must be missing something simple but how can I use NonlinearFit to finds the best fit for an equation who's next data point is the result of its current fit? Please excuse my lack of good english communication to communicate what I want, I just hope it's understandable. Has anyone a suggestion or a Mathematica text reference. -- David A.
