Analysis of Means for Proportions
If the response has two levels, you can use this option to compare response proportions for the X levels to the overall response proportion. This method uses the normal approximation to the binomial. Therefore, if the sample sizes are too small, a warning appears in the results.
Note:
For a description of Analysis of Means methods, see the document by Nelson, Wludyka, and Copeland (2005). For a description of the specific Analysis of Means for Variances method, see the paper by Wludyka and Nelson (1997).
Descriptions of the Analysis of Means for Proportions Options
Set Alpha Level
Selects the alpha level used in the analysis.
Show Summary Report
Produces a report that shows the response proportions with decision limits for each level of the X variable. The report indicates whether a limit has been exceeded.
Switch Response Level for Proportion
Changes the response category used in the analysis.
Display Options
Shows or hides the decision limits, decision limit shading, center line, and point options.
