DataFitting is a powerful statistical analysis program that performs linear and nonlinear regression analysis (i.e. curve fitting). DataFitting determines the values of parameters for an equation, whose form you specify, that cause the equation to best fit a set of data values. DataFitting can handle linear, polynomial, exponential, and general nonlinear functions.

DataFitting performs true nonlinear regression analysis, it does not transform the function into a linear form. As a result, it can handle functions that are impossible to linearize such as:

y = (a - c) * exp(-b * x) + c

Quickly Find the Best Equations that Describe Your Data:
DataFitting gives students, teachers, engineers, researchers and other professionals the power to find the ideal model for even the most complex data, by putting a large number of equations at their fingertips. It has built-in library that includes a wide array of linear and nonlinear models from simple linear equations to high order polynomials.

Graphically Review Curve Fit Results:
Once your data have been fit, DataFitting automatically sorts and plots the fitted equations by the statistical criteria of Standard Error. You can preview your graph and output publication-quality graphs in several different configurations. A residual graph as well as parameter output is generated for the selected fitted equation. Data, statistical and numeric summaries are also available from within the report-panel.

DataFitting has the following capabilities:
* 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.

Featured Application
XUpload is an advanced progress bar indicator for web based file uploads written on Perl. XUpload lets you to accept file uploads on your website and shows upload progress bar which is showing upload progress in real-time. Upload progress bar could be shown in popup window or right on the upload page. It also shows upload progress in percents, upload speed (kb/s), elapsed and remaining time, size of uploading files (useful when uploading multiple files). You can stop file upload process by just pressing stop button. If file transfer will fail during upload process - error message will be shown. XUpload will work on any hosting, virtual/shared or dedicated and on all platforms driven by Apache Web Server - Linux or Windows. Read more \| Free Demo Downlaod
