Curve Fit Selection

When a file contains Variables data, the Analysis Options dialog box provides for definition of the curve fit to be applied to Individual-X control limits and Process Capability estimates. Each of the Curve Fit types will likely yield different results.

The available curve fit options include:

Best Fit (Johnson)

Weibull

Normal

Folded Normal

True-position

None:
Use this option to show no distribution on histograms, with no subsequent capability estimates shown.
