CurvFit 5.11.5
CurvFit (tm) is a curve fitting program 4 Windows. Lorentzian, Sine, Exponential & Power series are available models to match your data. A Lorentzian series is highly recommended for real data especially for multiple peaked/valleys data. CurvFit is another improved productivity example do to using Calculus (level) programming ... ie. minutes to solve, days or years to understand solution & what it implies (e.g. wrong model, sampling rate error).

Regression analysis - CurveFitter 1.3
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.

Equation graph plotter - EqPlot 1.3
Graph plotter program plots 2D graphs from complex equations. The application comprises algebraic, trigonometric, hyperbolic and transcendental functions. EqPlot can be used to verify the results of nonlinear regression analysis program. Graphically Review Equations: Equation graph plotter gives students, teachers, engineers and researchers the power to graphically review equations, by putting a large number of equations at their fingertips.

Regression Analysis - DataFitting 1.7
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.
