Easy CurveFit
License: Shareware

"Easy CurveFit" is a very easy tool to fit curve. Only three steps you should do, and you'll get the fitting curve and the needed parameters. The models include linear and nonlinear. Regressions: 1. Linear Fit, y=a+bx; 2. Quadratic Fit, y=a+bx+cx^2; 3. Compound Fit, y=ab^x; 4. Logatithmic Fit, y=a+b*ln(x); 5. Exponential Fit, y=a*exp(bx); 6. Power Fit, y=a*x^b; 7. Inverse Fit, y=a+b/x; 8. hyperbola Fit, y=ax/(b+x); 9. Geometric Fit, y=ax^(bx); 10. Geometric Fit, y=ax^(b/x);.

EASY-FIT Express
License: Freeware

The software system solves constrained nonlinear parameter estimation problems. Synonyms are data fitting, nonlinear regression, parameter identification, curve and surface fitting. The numerical methods are based on highly efficient Gauss-Newton-SQP algorithms. Model functions are defined in a modeling language called PCOMP and are interpreted and evaluated during runtime.

General: Arbitrary fitting criteria depending on parameters to be estimated, additional nonlinear equality or inequality constraints, and optionally on a second independent model variable

Numerical routines: Gauss-Newton-type SQP methods, automatic differentiation, alternative norms (sum of absolute values, maximum of absolute values), confidence intervals for estimated parameters, correlation and covariance matrix, identification of significance...

EASY-FIT ModelDesign
License: Demo

The system solves constrained nonlinear parameter estimation (nonlinear regression, data, curve and surface fitting) problems based on ODEs, DAEs, PDEs, PDAEs, steady-state systems, Laplace equations, and analytical functions. A statistical analysis provides confidence intervals, correlation and covariance matrix, identification of significant parameters, and allows optimum experimental design. Model equations are defined in a modeling language called PCOMP and are interpreted and evaluated during runtime.

SPtrack
License: Freeware

SPtrack is a GUI (Graphical User Interface) based program written in Matlab which is used for tracking single particles and finding Diffusion properties. It works on Matlab 6 and above platforms and requires the Image Processing Toolbox and the Curve fitting Toolbox (optional). The program analyzes each particle in an image sequence and then fits the centre of the particle. The key feature of the program is its GUI based approach which is very user friendly and gives the user the freedom to analyze the data in more than one way.

GUI for Generalized Nonlinear Non-analytic Chi-Square Fitting
License: Freeware

FitChiTool provides an interface similar to the Curve Fitting Toolbox to the fitChiSquare function. This allows you to perform fits using chi-square when measurement errors are known on linear or nonlinear models. It allows allows you to perform fits with multiple independent (more than one x) variables. If measurement errors are unknown, it performs nonlinear least-squares fitting (chi-square equal to 1). To get started with FitChiTool, run the tutorial in the included HTML documentation (or run FitChiToolExample).

NLREG
License: Demo

NLREG performs nonlinear regression and curve fitting. NLREG fits a mathematical function whose form you specify to a set of data values. Virtually any type of function can be fitted. NLREG includes a programming language similar to C that you use for describing the function to be fitted. Two dimensional line and three dimensional surface plots can be generated. The programming language includes a large selection of built-in library functions (sin, cos, log, exp, etc.) that makes it easy to describe complicated models.

DataFit
License: Shareware

DataFit is a tool used to perform nonlinear regression (curve fitting), statistical analysis and data plotting. What sets DataFit apart from similar curve fitting and regression programs is its ease of use. DataFit is driven by a well-designed graphical interface, so there are no complicated instructions to remember and no programs to write. Data entry is achieved through a standard spreadsheet interface, which supports ASCII and ODBC data source import, as well as cutting and pasting data from the clipboard.
