The Simple Fit-engine uses Scipy's leasqr 13 and the Complex Fit-Engine is a custom optimizer that provides a better chance 14 to find the global minimum of the chi2 but that requires longer computation time. 15 In order to set a data to a control panel (FitPage), see the "DataLoader Help". 16 Once a data set to the FiPage, select a model from the combo box. 17 The default parameters of the model will be display. Set initial parameters if need. 18 Check and uncheck parameters to fit/fix. Click the <b> 'Fit'</b> button. 19 When the fitting is finished, the resultant parameter values will be displayed with the errors. If a error is missing, it generally means 20 that the corresponding parameter is not very depending on the model. The chisq/Npt_fit and the plot associated 21 with the fit operation will be also updated. 25 22 26 23 </p>
