A method and apparatus is provided for the calculation of maverick control limits. The maverick control limit method selects the correct parameter(s) as critical parameters to be utilized by the maverick control limit method. Next, the maverick control limit method identifies the probability density function that is associated with the parametric data set(s) that are associated with the critical parameter(s). Next, abnormal data points within the measured parametric data set(s) are removed. Maverick control limits are then calculated to properly disposition semiconductor die into pass/fail categories.
