5) Go to "Data" Tab
6) Select "weight" of data point with concentration=0.6
- Set that weight to 0.0
7) Go back to "Simple Fit" Tab and hit "Curve Fit"
- Notice that the zero-weighted point is marked as such on the plot
- As the author predicts, the fit is greatly improved
- Surprisingly, XYmath shows the 3 term equation "y = c0 + c1*x + c2/x"
to be superior to the 4 term equations as well as the quadratic.
