Description

General description

Automate the difficult task of finding the best equation to fit experimental data. Import data as ASCII files or from Lotus, Excel, or Quattro Pro spreadsheets. Then TableCurve, in a single processing step, fits the data to all of its built-in equations and ranks them by correlation coefficient. View results as graphs or numeric summaries. Output hardcopy graphs or create a file of fit results. Choose TableCurve 2D if your data involves curve-fitting two-variable (x,y) data; TableCurve 3D for surface-fitting three-variable (x,y,z) data.

TableCurve 3D® gives scientists the power to find the ideal model for even the most complex data, including equations that might never have been considered. TableCurve 3D�s built-in equation set includes a wide array of linear and nonlinear models for any application:
• Linear equations
• Polynominal and rational functions
• Logrithmic and exponential functions
• Nonlinear peak functions
• Nonlinear transition functions
• Nonlinear exponential and power equations
• User-defined functions (up to 15)
TableCurve 3D�s state-of-the-art surface fitting includes capabilities not found in other software packages:
• 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
• Option to change the maximum number of terms permitted when fitting linear equations (minimum 3; maximum 11)
• 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 set the default term significance anywhere from 1 to 15.
