Data Curve Fit Creator Add-in is an easy-to-use data analysis add-in for Microsoft Excel. It adds curve fitting, interpolation, and data smoothing functions to Excel. Curve fitting functions include polynomial fits and a versatile local regression (loess) function. Interpolations include linear, cubic spline, bessel and monotonic \'constrained\' splines, as well as a \'flexible spline\' that allows you to specify the slope at each data point. Cubic spline function coefficients and slope can also be returned.

Auto2Fit is a robust, flexible, easiest-to-use regression, curve fit, global optimization, equation solving and parameter estimation program by using Evolution Algorithms (EAs). It is especially useful for the complicated jobs that are hard or impossible to be solved by regular/traditional approaches. Application Areas: Auto2Fit can be used in the areas such as: 1. Regression and Curve Fit: linear, nonlinear, multi-nonlinear with no limitations on variable and parameter number 2. Global Optimization: find the maximal/minimal value of any function.

Curve Fitter is a practical application that allows you to visualize and to fit data imported from CSV files. The program allows you to edit the data that you want to fit by manually selecting and deleting the points that you want to exclude.

You can examine a certain fragment from the data file by browsing the raw data or by selecting a part of the generated plots. The program also includes a scripting console program that allows you to access all the data fitting and visualization tools.

CurveExpert Professional is a cross-platform solution for curve fitting and data analysis. Data can be modelled using a toolbox of linear regression models, nonlinear regression models, smoothing methods, or various kinds of splines. Over 60 models are built-in, but custom regression models may also be defined by the user. Full-featured publication-quality graphing capability allows thorough examination of the curve fit. The process of finding the best fit can be automated by letting CurveExpert compare your data to each model to choose the best curve.

A GUI wich use the matlab core function "fminsearch" to fit data with any multivariable function (with a "live" visualisation of the moving fitted curve). This function can be run with real equations, complex equations, and all other functions like step and bode. Simple to use..

DataFitting is a powerful statistical analysis program that performs linear and nonlinear regression analysis (i.e. curve fitting). DataFitting determines the values of parameters for an equation, whose form you specify, that cause the equation to best fit a set of data values. DataFitting can handle linear, polynomial, exponential, and general nonlinear functions. DataFitting performs true nonlinear regression analysis, it does not transform the function into a linear form. As a result, it can handle functions that are impossible to linearize such as: y = (a - c) * exp(-b * x) + c Quickly Find the Best Equations that Describe Your Data: DataFitting gives students, teachers, engineers, researchers and other professionals the power to find the ideal model for even the most complex data, by putting a large number of equations at...

CurveFitter program performs statistical regression analysis to estimate the values of parameters for linear, multivariate, polynomial, exponential and nonlinear functions. The regression analysis determines the values of the parameters that cause the function to best fit the observed data that you provide. This process is also called curve fitting. Fit thousands of data into your equations in seconds: Curvefitter gives scientists, researchers and engineers the power to find the ideal model for even the most complex data, including equations that might never have been considered.

This GUI converts an image of a curve into data points relatively quickly, even if the original image contains grid in the background. The way to use it is very simple. 1)open an image 2)choose scale parameters 3)choose Image processing parameters (default values can often be sufficient) 4)Start reconstitution 5)After removing the grid or annotations automatically, you can clean the resulting b&w image with the eraser tool 6)Finish reconstitution by creating the curve and see if you are satisfied.

This is free software that adds several spline and linear interpolation functions to Microsoft Excel. It is simple to use because the new functions work just like all other existing Excel functions. Spline functions include cubic spline, bessel spline, and 'OneWay' spline (which is a monotonic spline). The new functions can be used for data analysis, forecasting, and many other applications. See SRS1Software.com for demos and more information. Video demos showing how to use the product are also on the website.

LAB Fit is a software for Windows developed for treatment and analysis of experimental data. At LABFit program you are able to: 1) Treat similar data (grouped and ungrouped dataset, one or two samples); 2) Treat non-similar data; 3) Determine propagated error (error propagation up to eight independent variables); 4) Plot 2D and 3D graph (normal, parametric, imported dataset, contour of maps); 5) Execute math calculations (system of linear equations, roots of function, non-linear equation, ordinary differential equation - ODE up to fifth order, system of differential equations - up to five first order ODE, calculator, etc); 6) Extract data (x;y) from a 2D graph (digitizing); 7) Curve Fit (nonlinear regression - least squares method, Levenberg-Marquardt algorithm - with almost 500 functions at the library, with 1 and 2 independent...

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.
