FindGraph is an engineering and science tool that simplifies the task of curve fitting and regression analysis. FindGraph supplies 10 generic fits, including Linear Regression, Logistic Functions, Fourier approximation, Neural Networks plus a library of over 200 built-in functions selected from different areas of research and development. The Wizard of Approximation will help you to apply a variety of curve fits to your plot to discover the best model to describe your data. With FindGraph, even a statistical novice can find the best equation in just a few minutes. All fits are calculated with incredible speed and accuracy. You can fit data to lines or curves. Regression curve fits are 1st to 20th order polynomial, power, exponential, or log. The program uses several non-linear least-square curve fitting algorithms. The simplex and Levenberg-Marquardt algorithms were used for quick nonlinear regression performance. Neural network approximation is equally suited for advanced and inexperienced users. You can input desirable formula (analytical function) and vary the number of parameters. You can use your own curve fitting algorithms as plug-ins. FindGraph uses parametric equations X(u), Y(u) to fit data with closed curves. Interpolation options include Lagrangian polynomials and Cubic splines. Interpolations and curve fitting in polar coordinates are possible.
