Problem Note 9597: Incorrect NORMALTEST and PNORMAL inset values in comparative plots
When the NORMALTEST and PNORMAL options are specified on an INSET
statement for a COMPHISTOGRAM plot in PROC CAPABILITY, incorrect results
for the Shapiro-Wilk's W test statistic and its p-value are displayed in
every cell except the last one. All cells of the comparative plot will
contain the statistics from the last cell. The Shapiro-Wilk test is
only computed when there are less than or equal to 2000 observations in
the analysis variable, and the W statistics and p-values are correct in
both the printed output and the output data set.
To circumvent the problem, specify BY and HISTOGRAM statements instead
of a COMPHISTOGRAM statement with the CLASS= option.
