The Linearity Study performs a regression analysis using the standard variable as the X variable and the bias as the Y variable. This analysis examines the relationship between bias and the size of the part. Ideally, you want to find a slope of zero. If the slope is significantly different from zero, you can conclude that there is a significant relationship between the size of the part or variable measured as a standard and the ability to measure.

The Linearity Study option is available only when a Standard variable is provided in the launch window.

Produces separate linearity plots for each level of the X, Grouping variables that you specified in the launch window.
