| 12 | One of two fit-engines can be chosen from the Fitting menu bar. 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. |
