CurveExpert Professional is a cross-platform solution for curve fitting and data analysis. Data can be modeled using a toolbox of linear regression models, nonlinear regression models, smoothing methods, or various kinds of splines. Over 60 models are built-in, but custom regression models may also be defined by the user. Full-featured publication-quality graphing capability allows thorough examination of the curve fit. The process of finding the best fit can be automated by letting CurveExpert compare your data to each model to choose the best curve.

What is new in this release:

  • RESOLVED: Fixed license non-validation issues (both trial and paid customers). MSVCRT100.dll was not properly included in the distribution. (Windows only)
  • RESOLVED: updated syntax for the Steinhart-Hart equation
  • RESOLVED: an incorrect check in the export table dialog caused erratic behavior (An error that complained that a file could not be found) when "Data" was selected as the source of the x data.

What is new in version 2.6.2:

Version 2.6.2:

  • NEW: Five new Yield-Density models added (thanks Charles Tomkins for the model list), and previous Yield Density models have been moved to the Yield-Spacing family.
  • NEW: changed the strategy for the "Top Results" plot. It now always displays only the top results (the number of which is configurable in the application preferences). Previously, the plot would always add the top results from any new calculations the user might perform, which was confusing.
  • NEW: When right clicking a result, there is a new menu option "Add to New Plot" when appropriate. This creates a new plot and sends the result(s) there in one step. When a plot is created in this way, the title of the plot is that of the first result sent to it (for example, "Modified Exponential"). The "Add to Plot" option in the menu has been renamed to "Add to Current Plot" also.
  • NEW: Expand/Collapse buttons added in the Nonlinear Regression selection dialog, so that it is easier to select just a couple of families from the library.
  • NEW: Better robustness for 15 of the nonlinear regression models, so that the initial guess mechanism may be able to survive a zero in the x or y columns of the dataset.
  • RESOLVED: If the residual history had a NaN, the Convergence tab would not appear properly (with a small white box) in the result details dialog. Fixed.
  • RESOLVED: in some situations, obviously failed models were showing with a status of OK. Fixed.
  • RESOLVED: for users with non-ascii codes in their user names, CurveExpert Pro would fail to start. Fixed.

What is new in version 2.5.3:

Version 2.5.3:

  • Added ability for user to build table in multiple ways: from a file with the desired x values, from a xstart/xstop/npoints triple, from a xstart/xstop/dx triple, and from the current data in the dataset.
  • Added "Export Table" to the right click menu in the Results pane. This makes it easier to quickly create tables without having to open the Result Details dialog.
  • Added "Copy Parameters" and "Copy All Info" to the right click menu in the Results pane. This makes it easier to get parameters and model information out of CurveExpert Pro into another application (such as Excel).
  • improved the user interface in the Create Table dialog.
  • --license -license_file_name- and --quit command line options added for administrators who desire to apply licenses in an automated fashion.
  • Resolved: PS/EPS files were not correctly output under Windows. Fixed.
  • Resolved: unnecessary console window "flashes" eliminated when the program checks for new versions online
  • Resolved: Slight adjustment to the location of popup menu in the result control under Linux.

What is new in version 2.4:

In CurveExpert Professional, the primary addition is the ability to weight a regression (both linear and nonlinear) by other factors other than the square of the standard deviation. Now, CurveExpert Pro supports weighting by y, y^2, x and x^2 in addition to the default weighting behavior (which is to not weight if there is no standard deviation data, and to weight if there is). The full changelog for CurveExpert Professional is as follows:

  • NEW: added support for weighting nonlinear and linear regressions, including the CurveFinder tool.
  • NEW: polynomial regressions and linear regressions now have appropriate statistics shown in the tooltip (standard error, correlation coefficient, etc).
  • RESOLVED: if a user uses x1 in a 2D model (alone), the generated code was not correct. Resolved.

What is new in version 2.3.0:

  • NEW: Added the ability digitize datasets from a source image. The digitized data becomes the main dataset that is operated on in CurveExpert Pro.
  • NEW: added Savitzky-Golay smoothing
  • RESOLVED: when drawing a line on a log plot, the points were not evenly spaced in log scale. Fixed.
  • RESOLVED: transparency setting was lost from a contour once the graph properties dialog was exited. Fixed.
  • RESOLVED: import of noisy_sin.dat, which had special tags at the top of the file, gave these special lines as the column headers. Fixed.
