XL fit 4

By R&D Editors | January 31, 2004

XL fit 4

XLfit 4 is a software package for automated curve fitting and statistical analysis within the Microsoft Excel spreadsheet environment. The United Kingdom’s National Physical Laboratory (NPL) has tested the numerical correctness of the curve-fitting component of the software. In addition to newly validated models, it offers new and interactive chart types including 3-D fitting and global fitting, and enhanced mathematical methods and techniques. The software comes with an extended range of models such as 3-D fitting and charting, PA2, global fitting and automatic outlier rejection. These models allow researchers to entirely automate the fitting processes without leaving Excel and to generate the required results quickly.
