    SN-008065 ***Alert Sas Note***

    Kendall Partial Tau b Correlation Coefficients are incorrect when a
    variable has zero variance and the PARTIAL statement is used

    Product: Base SAS
    Component: CORR procedure
    Priority: ALERT

      If you are using a PARTIAL statement, and if any of the analysis
      variables have a standard deviation of zero, then the Kendall Partial
      Tau b Correlation Coefficients are incorrect. The coefficients that are
      produced are actually the unpartialed Kendall's Tau b correlations.

      To circumvent the problem, remove the variables for which the STD Dev is
      zero.
