You can also automatically display a 2D contour plot on the top and bottom of the surface fit graph to get another view of your data. Add confidence or prediction intervals to the graph to detect outliers in your data. A 3D residuals graph as well as parameter output are generated for each fitted equation. Graphically review the fitted results as you scroll through the equation list. Once your XYZ data have been fit, TableCurve 3D automatically sorts and plots the fitted equations by the statistical criteria you select (r2, DOF adjusted r2, Fit Standard Error or the F Statistic). For maximum flexibility, TableCurve 3D gives you the option to save your functions as individual files, in libraries or both. Unlike most surface fitting programs, TableCurve 3D’s user-defined functions are compiled so they can be fitted at nearly the speed of the built-in equations. TableCurve 3D even offers the option of graphically adjusting equation parameters to assure convergence for the fit of user-defined models. These specialized models can contain most mathematical constructs, including special functions, series convergence and conditional statements, differentiations, integrations and parameter constraints. Up to 15 user-defined equations can be entered and ranked along with the built-in equations. Option to set the default term significance anywhere from 1 to 15.Īutomation Takes The Trial And Error Out Of Curve Fitting.On systems that support multi-threading, TableCurve 3D’s Background Thread Processing option allows fitting to occur without any form of user input.Option to change the maximum number of terms permitted when fitting linear equations (minimum 3 maximum 11).In addition to standard least squares minimization, TableCurve 3D’s non-linear engine is capable of three different robust estimations: least absolute deviation, Lorentzian minimization and Pearson VII Limit minimization.TableCurve 3D’s state-of-the-art surface fitting includes capabilities not found in other software packages: Nonlinear exponential and power equations.TableCurve 3D’s built-in equation set includes a wide array of linear and nonlinear models for any application: TableCurve 3D® gives scientists and engineers the power to find the ideal model for even the most complex data, including equations that might never have been considered. What once could take days of tedious work now takes minutes, with a much more powerful result.įind Optimum Equations to Describe Empirical Data TableCurve 3D uses a selective subset procedure to fit 36,000 of its 453,697,387 built-in equations from all disciplines to find the one that provides the ideal fit – instantly! TableCurve 3D is the first and only program that combines a powerful surface fitter with the ability to find the ideal equation to describe three dimensional empirical data.
