DataFit 8.1

DataFit is an advanced and reliable science and engineering program which will simply the data plotting operations, statistical analysis and regression analysis.The program is very easy to use and provides a rich set of features. Moreover, the user-friendly and intuitive interface makes it accessible to both beginners and experts.

DataFit comes with a wide variety of features and tools, allowing you to better handle your data with minimum effort.

DataFit allows you to import data from a wide variety of ODBC sources, such as dBase, Oracle, Visual FoxPro, MS Access, Excel, Paradox, and SQL Server. Non-linear and linear regression models having maximum 20 independent variables can be solved by using this program.

DataFit integrates Backward Elimination, Manual, Forward Selection, and Stepwise Selection variable selection modes, allowing you to easily determine what independent variables must be included in the regression model. In addition, the application comes with 242 three-dimensional and 298 two-dimensional pre-defined nonlinear regression models.

DataFit allows you to define your own regression models. You can define models having up to 100 fitting variables and parameters. The application performs nonlinear regression by using the Levenberg-Marquardt method.

DataFit will monitor each step in the regression process and will generate reports containing detailed data about your tasks. If the models is not solved, the program offers diagnostics data in order to help you identify the issue.
