Curve Fit Table Results Dialog
Once a curve fit has been established, the quality of the fit can be assessed by examining the results in the Curve Fit Table Results Dialog.
The values of the best fit coefficients and their standard error (expressed both as an absolute and relative value) are reported in the upper table. The lower table provides various statistics.
