You can choose additional options for non-normal data.
Non-normal slices
To allow GainSeeker to repeatedly "slice" the curve of the distribution until a low error coefficient is reached, select Unlimited. For unusual data distributions, this can substantially slow the analysis.
To limit the number of slices, select Limited. GainSeeker's approximation of the non-normal area may not fit as closely to the actual curve of the data, but the data can be processed more quickly.
Method to calculate Z values
Z values are used to calculate Cpk, Cp and CR for uniformly distributed data and for non-normal data that can be modeled.
You can choose to have the program calculate Z values from the Median or from a table (Probability method).
For more information on these two methods, see Flow Chart Analysis of Non-Normal Data.
If you selected Analysis Mode 2 on Chart Wizard Step 1, one more option is available:
To apply the selected options to all part numbers or Short Run process specifications that you selected on Chart Wizard Step 1, select the Apply to all items in selected values list check box.
To apply the selected options only to the values you selected on Chart Wizard Step 3 for retrieval and statistical options, clear the Apply to all items in selected values list check box.
After making your selections, click OK to keep your changes or Cancel to undo your changes. You will then be returned to Statistical Options Wizard Step 3.
