Quickly Find the Best Equations
that Describe Your Data
TableCurve 2D®
gives engineers and researchers the power to find the ideal model
for even the most complex data, by putting thousands of equations
at their fingertips. TableCurve 2D's built-in library includes a
wide array of linear and nonlinear models for any application including
equations that may never have been considered. - from simple linear
equations to high order Chebyshev polynomials. TableCurve 2D is
the automatic choice for curve-fitting and data modeling for critical
research. TableCurve 2D’s state-of-the-art data fitting includes
capabilities not found in other software packages:
A 38-digit precision math emulator for properly fitting high
order polynomials and rationals.
A robust fitting capability for nonlinear fitting that effectively
copes with outliers and a wide dynamic Y data range.
An AI Expert option that automatically selects the appropriate
peak, transition or kinetics models for you.
Automation Takes The Trial and Error
Out of Curve Fitting
Fit all of
TableCurve 2D’s 3,665 built-in equations or just the ones you need
— instantly! With TableCurve 2D, a single mouse click is all it takes
to start the automated curve fitting process there is no set up required.
TableCurve saves you precious time because it takes the endless trial
and error out of curve fitting.
Fit User Defined Equations
Up to 15 user-defined
equations can be entered and ranked along with the built-in equations.
These specialized models can contain most mathematical constructs,
including special functions, series convergence and conditional statements,
differentiations, integrations, and parameter constraints. And, unlike
most curve fitting programs, TableCurve 2D's user-defined functions
are compiled so custom curve fitting can be performed quickly -- at
nearly the speed as with the built-in equations. You can also add
up to 100 external C or FORTRAN language functions to the TableCurve
2D equation set. These equations and constraints can be of unlimited
complexity.
Accurately Extrapolate Any Data Set
Increase the accuracy
of your predictions with state-of-the-art AR (Autoregressive) procedures
that offer the means to effectively extrapolate any data set. Select
from any one of the 9 different procedures for extrapolating your
data - 3 to predict ahead, 3 to predict earlier data, and 3 that
predict in both directions. Of these algorithms, six offer in-situ
noise removal using advanced SVD and Eigendecomposition methods.
All the Tools you
Need to Visually Discover your Best Model :
Graphically Review Curve Fit Results
Once your XY data have
been fit, TableCurve automatically sorts and plots the fitted equations
by the statistical criteria you select (r2, DOF adjusted r2, Fit Standard
Error or the F Statistic). Graphically review the fitted results as
you scroll through the equation list. A residuals graph as well as
parameter output are generated for each fitted equation. Add confidence
and prediction intervals to the graph to detect outliers in your data.
Data, statistical and numeric summaries are also available from within
the Review Curve Fit window so you can further analyze fit results.
TableCurve gives you all the information you need to discover the
model that best meets your requirements for the ideal fit.
Compare Models Using Meaningful Numeric
Information
Data, statistical and
precision summaries are available so you can further analyze fit results.
These summaries can be simultaneously displayed and are automatically
updated when a different equation is selected for review. Evaluation
option with automated table generation, includes function, derivatives,
roots and cumulative area.
Effectively Manage Complex Data Sets
TableCurve
2D offers state-of-the-art smoothing and denoising techniques to remove
the noise in your data. Select from a total of 6 smoothing/denoising
algorithms. Of special importance is the Eigendecomposition Denoising,
a non-parametric procedure where separation is based on signal strength.
For Fourier Denoising, TableCurve 2D offers a data taper to minimize
spectral leakage and the means to filter either by the magnitude of
FFT channels or by frequency threshold. Inspect analytic derivatives
for all built-in equations, as well as all of the smoothing procedures.
Mask outliers and refit your data. With TableCurve 2D, its all so
easy!
Precisely Model Exotic Data Sets
For those rare equations that
cannot be adequately managed by a parametric model, TableCurve 2D
offers three non-parametric estimation procedures. The Spline, Smoothing
Spline and Local Regression options offer true state-of-the-art algorithms.
For example, there are seven different spline algorithms, including
two least-squares minimizations and the non-uniform n.
Flexible Output Options
With TableCurve you can preview
your graph and output publication-quality graphs in several different
configurations. You can also produce files containing data and equations
in Lotus, Excel, ASCII, Harvard Graphics and SigmaPlot formats. TableCurve
2D can speed up your programming by generating actual function code
and test routines for all fitted equations in FORTRAN, C, Basic, Pascal
and VBA for Excel.
Maximize Your Productivity With Automation
Save time with the new unattended batch
processing capability to automatically process a large number of data
sets - no programming required! With this integrated automation capability,
you can analyze a large number of data sets while you are away from
your PC! TableCurve 2D automatically generates the output for each
data set. The output can be written to an MS Word (or generic RTF)
file for all graphs and numeric summaries, and to MS Excel for numeric
data. The automation capability is available for all of TableCurve
2D's major procedures.
