![]() ![]() But, I think the solver is a very handy feature and, therefore, I want to give here a short introduction into using it for fitting a sigmoid function to a set of data.įirst, we need a set of data. It is possible to do such fits for nearly any function using the solver, though, but only a few people I’ve met knew how to do this or that it is even possible. However, both lack the possibility to fit sigmoid functions, automatically. Personally, I use Origin/QtiPlot only for plotting and Excel/OO–Calc for evaluation/calculation, because both programs are much more comfortable and powerful. So, people use software such as Origin or QtiPlot to fit. ![]() Nevertheless, it is hard to guess the parameters for a given problem. ![]() Last week, I posted an article about sigmoid functions and how to use them. ![]()
