Macro capability allows curve fitting operations to be performed non-graphically, either in batch mode or by calling DataFit from an external program. You can also automatically export source code in BASIC or C to utilize any solved equation in a program that you have written. Data tables, supporting interpolation and extrapolation (projections), can be exported in ASCII, Excel or HTML format. Plots can be saved as templates, which allows them to be applied to new plots in order to instantly give them your own custom appearance.
estimated data and goodness-of-fit information. Results include completely customizable 2D and 3D plots, fitted parameters with confidence intervals, input vs. DataFit also includes forward selection, backward elimination, stepwise selection and manual variable selection modes to help determine which independent variables should be included in your regression model for multivariate datasets. Solved equations are sorted according to goodness-of-fit.
You can choose from more than 600 pre-defined equations, which are commonly used in statistical, scientific and engineering applications, or create your own equations. With DataFit, you can perform linear or nonlinear regression on data containing up to 20 independent variables. 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.
DataFit is driven by a well-designed graphical interface, so there are no complicated instructions to remember and no programs to write. What sets DataFit apart from similar curve fitting and regression programs is its ease of use. DataFit is a tool used to perform nonlinear regression (curve fitting), statistical analysis and data plotting.
