This curve fitting analysis tool from Daniel G. Hyams also comes with it’s own EPUB manual. The current documentation is only available for the basic app and although a little rough around the edges, it does present all the information along with an appropriate EPUB Table of Contents.
Daniael is currently developing a new version, CurveExpert Professional, and hopefully he will also iron out those rough edges on the manual.
Information on the Software
CurveExpert is a curve fitting software tool which employs a large number of both linear and nonlinear regression models, various interpolation schemes and splines to represent XY data in a very precise manner.
CurveExpert has over 30 built-in regression models while also allowing for the design of custom models. Full-featured graphing capabilities allow a thorough examination of the curve fit and CurveExpert can automatically find the best fit; comparing your data to each model to choose the best curve.
