TableCurve 3D-建模复杂数据集快速简便

tcurve3d_graph2

使用TableCurve 3D消除乏味的数据分析苦差

TableCurve 3D是结合了强大的曲面拟合器和找到描述三维经验数据的理想方程的能力的第一个也是唯一的程序。

TableCurve 3D使用一个选择性的子集过程来从其所有内置的453,697,387个方程式中拟合36,000个,以找到一个提供理想拟合的方程!

曾经花费数天的繁琐的工作现在需要几分钟的时间,效果更加强大。

找到最优方程来描述经验数据

TableCurve3D®使科学家和工程师有能力为甚至最复杂的数据找到理想的模型,包括可能从未考虑过的方程式。 TableCurve 3D的内置方程组包括用于任何应用的各种线性和非线性模型:

•线性方程
•多项式和有理函数
•对数和指数函数
•非线性偏函数
•非线性峰值函数
•非线性转换函数
•非线性指数和幂方程
•用户自定义函数(多达15个)

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.

Automation Takes The Trial And Error Out Of Curve Fitting

Using its selective subset procedure, TableCurve 3D will fit 36,000 of the over 450 million built-in equations or just the ones you need – instantly. With TableCurve 3D, a single mouse click is all it takes to start the automated curve fitting process – there is no set up required! You can even enter your own specialty models to be fit and ranked along with the built-in equations. TableCurve saves you precious time because it takes the endless trial and error out of curve fitting.

用户自定义函数

big_residualUp 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. TableCurve 3D even offers the option of graphically adjusting equation parameters to assure convergence for the fit of user-defined models. 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. For maximum flexibility, TableCurve 3D gives you the option to save your functions as individual files, in libraries or both.

Visually Discover the Best Equation to Model your Data: Graphically Review Surface Fit Results

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). Graphically review the fitted results as you scroll through the equation list. A 3D residuals graph as well as parameter output are generated for each fitted equation. Add confidence or prediction intervals to the graph to detect outliers in your data. 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. Data, statistical and numeric summaries are also available from within the Review Surface Fit window so you can further analyze fit results.

最佳拟合

Viewing a surface fit from all angles is imperative in determining whether or not a given fit is accurate. Using a simple interface, TableCurve 3D lets you view a graph from any angle. It will even animate the graph automatically in a specified XY and/or Z angle sequence. Just sit back and observe every nuance within the fit. TableCurve 3D gives you all of the tools you need to discover the model that best meets your requirements for the ideal fit.

灵活的输出选项

输出TableCurve 3D的黑色和白色或彩色,纵向或横向的出版质量的图形。 您还可以在Lotus,Excel,ASCII,Quattro Pro和SigmaPlot格式中生成包含数据和方程式的文件。 TableCurve 3D可以以FORTRAN,C,Basic和Pascal语言为所有拟合方程生成实际的功能代码和测试例程来加快编程速度。

All This Power - and Still Easy to Use!

TableCurve 3D takes full advantage of the Windows graphical user interface to simplify every aspect of operation – from data import to output of results. Import data from many popular file formats including SigmaPlot, Excel, Lotus, SPSS and ASCII. Once your data are in the TableCurve editor, start the automatic fitting process with a single mouse click. Choose to fit all equations, select a group of equations or create a custom equation set. All equations are readily available from the Toolbar or TableCurve’s Process Menu. You can even set up TableCurve 3D to begin fitting the moment data are imported or modified with Background Thread Processing Fitting. Users consistently comment that – out of the box, without reading the instructions – TableCurve is highly intuitive, easy-to-use and remarkably simple to learn.
