This software provides a range of mathematical tools such as curve fitting, nonlinear regression, treatment of data, basic statistics, and error propagation. It also allows users to create 2D and 3D graphs with confidence band, uncertainty, error bars, and conduct tests such as chi-square and correlation coefficient. Additionally, it includes a covariance matrix for extrapolation.
LAB Fit is a Windows software designed for the analysis and processing of experimental data. With LABFit, you have the ability to treat grouped and ungrouped dataset, one or two samples, as well as non-similar data. LABFit enables you to determine propagated error up to eight independent variables and plot 2D and 3D graphs like normal, parametric, imported dataset, contour of maps.
In addition, LABFit can also execute math calculations, such as the 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, among others. LABFit also provides a way to extract data (x;y) from 2D graphs (digitizing) and perform Curve Fit through nonlinear regression using the least squares method, Levenberg-Marquardt algorithm - with almost 500 functions at the library, with 1 and 2 independent variables, functions finder, and an option that allows you to write the fit function.
Furthermore, LABFit provides the option to reject data, confidence and prediction bands. LABFit has a menu for curve fitting, where the primary programs of the menu utilize nonlinear regression. LABFit fits functions of one and several independent variables (from 1 up to 6) and admits uncertainties at the dependent variable (Y) and also at the independent variables (X). At LAB Fit library, users can choose from over 200 functions with one independent variable and almost 280 functions with two independent variables.
If a user cannot find a suitable function, LABFit provides a finder functions program, and there is an option so that the user can write its own fit function. Once you have determined the fit parameters, you can extrapolate the fit function with LABFit, and for the 2D and 3D cases, the graph of the obtained function is shown. For 2D cases, beyond the extrapolation possibility, the user can even include error bars and confidence bands to the graph.
Moreover, LAB Fit has a menu that allows you to treat similar data, non-similar data, and error propagation. The software provides a third menu with general tools like plotting a function informed by user. If you need software that provides a unique blend of data processing, analysis, and extrapolation functionalities, LABFit is one software product that you can trust.
