    SN-007889 ***Alert Note***

    Incorrect PROBPLOT and/or QQPLOT with missing values in PROC UNIVARIATE

    Product: Base SAS
    Component: UNIVARIATE procedure
    Priority: ALERT

      If there are any missing values for the analysis variable in PROC
      UNIVARIATE, the plots generated by the PROBPLOT and QQPLOT statements
      will be incorrect. Only the location of the plotted symbols will be
      incorrect. Note that all of the statistics are correct.

      To circumvent this problem, omit the missing values using a WHERE
      statement. However, this will also eliminate the Missing Values section
      of the output. If this information is needed, then run the PROC
      UNIVARIATE twice, once omitting the missing values and once without
      omitting them.

      If SAS/QC is available, the problem may also be circumvented by using
      PROC CAPABILITY.
