96 Mathcad Worksheets for Data Fitting
K. Schittkowski: Report, Department of Computer Science, University of Bayreuth
The purpose of the paper is to introduce a set of data fitting test examples in
form of Mathcad worksheets. The
availability of data fitting test problems is an important assumption to develop
and test least squares codes, to learn how optimization routines behave, or to
become familiar with implementation and user interface. The problems are taken
from a collection of test examples for data fitting in
The report contains a brief introduction and review on least squares methods,
moreover a summary of 96 data fitting test problems that have been transferred
to Mathcad and a detailed example. A
particular advantage of executing these problems from Mathcad is the possibility
to plot corresponding residuals easily.
