r5ac0a7a rff42a26 351 351 window, and a second graph window will appear displaying the residuals (the 352 352 difference between the experimental data and the theory) at the same X-data values. 353 See :ref:`Assessing_Fit_Quality`. 353 354 354 355 The objective of model-fitting is to find a *physically-plausible* model, and set … … 373 374 fit of the theory to the experimental data improves the value of 'chi2/Npts' will 374 375 decrease. A good model fit should easily produce values of 'chi2/Npts' that are 375 close to zero, and certainly <100. 376 close to zero, and certainly <100. See :ref:`Assessing_Fit_Quality`. 376 377 377 378 SasView has a number of different optimisers (see the section :ref:`Fitting_Options`). … … 397 398 *Send To Fitting*. Either way, the result should be that for *n* data sets you have 398 399 2\ *n* graphs (*n* of the data and model fit, and *n* of the resulting residuals). But 399 it may be helpful to minimise the residuals plots for clarity. 400 it may be helpful to minimise the residuals plots for clarity. Also see 401 :ref:`Assessing_Fit_Quality`. 400 402 401 403 *NB: If you need to use a customized model, you must ensure that model is available* … … 439 441 Note that the chi2/Npts value returned is the SUM of the chi2/Npts of each fit. To 440 442 see the chi2/Npts value for a specific *FitPage*, click the *Compute* button at the 441 bottom of that *FitPage* to recalculate. 443 bottom of that *FitPage* to recalculate. Also see :ref:`Assessing_Fit_Quality`. 442 444 443 445 Simultaneous Fits with Constraints … … 465 467 Note that the chi2/Npts value returned is the SUM of the chi2/Npts of each fit. To 466 468 see the chi2/Npts value for a specific *FitPage*, click the *Compute* button at the 467 bottom of that *FitPage* to recalculate. 469 bottom of that *FitPage* to recalculate. Also see :ref:`Assessing_Fit_Quality`. 468 470 469 471 .. ZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ … … 525 527 If you select a 'Chi2' value and click the *View Fits* button a graph of the 526 528 residuals for that data set is displayed. Again, if you select multiple 'Chi2' 527 values then all the residuals data will appear on one graph. 529 values then all the residuals data will appear on one graph.
