Curve-fitting and data analysis software that expands the power of Excel has been validated by the UK National Physical Laboratory
The United Kingdom's National Physical Laboratory (NPL) has worked with IDBS, provider of integrated data management, analysis and decision-making software, to test and validate the numerical correctness of the curve fitting component of XLfit 4 (curve-fitting and data analysis software that expands the power Excel).
The National Physical Laboratory's centre for mathematics and scientific computing develops and validates mathematical models and software, and offers independent services to aid the development of secure, reliable and robust IT systems. NPL considered sixteen specific curve fitting models from IDBS's XLfit 4.
The organisation generated ten reference data sets for each model and compared test results provided by IDBS for these data sets with reference results held by NPL. Independent validation by the NPL means that company statisticians can now validate XLfit quicker than other curve fitting packages.
"By extending the functionality of Excel and simplifying curve fitting, XLfit 4 provides a straight-forward and efficient way for researchers to carry out their statistical analysis within the familiar spreadsheet environment," commented Neil Kipling, chairman and CEO of IDBS.
"We are pleased to offer users the added confidence of the National Physical Laboratory's validation of the curve fitting component".
Adept Scientific supplies and supports XLfit 4 in the UK and Ireland, and also in the USA, Canada, Germany, Switzerland, Austria, Denmark, Sweden, Norway, Iceland and Finland.
