\subsection{Linear fits}
|
|
\begin{itemize}
|
|
\item Polyfit is easy: unique solution!
|
|
\item Example for overfitting with polyfit of a high order (=number of data points)
|
|
\end{itemize}
|
|
|
|
\section{Fitting in practice}
|
|
|
|
Fit with matlab functions lsqcurvefit, polyfit
|
|
|
|
|
|
\subsection{Non-linear fits}
|
|
\begin{itemize}
|
|
\item Example that illustrates the Nebenminima Problem (with error surface)
|
|
\item You need got initial values for the parameter!
|
|
\item Example that fitting gets harder the more parameter yuo have.
|
|
\item Try to fix as many parameter before doing the fit.
|
|
\item How to test the quality of a fit? Residuals. $\chi^2$ test. Run-test.
|
|
\end{itemize}
