    V6-MIXED-G978 ***Alert Note***

    PROC MIXED Reports Incorrect Satterthwaite DF with Heterogeneous TYPE=

    Product: STAT
    Component: MIXED
    Priority: HIGH

      PROC MIXED will report incorrect degrees of freedom when DDFM=
      SATTERTHWAITE or DDFM=KR is used with a heterogeneous covariance
      structure (CSH, ARH(1), or TOEPH) in conjunction with the SOLUTION
      option on the RANDOM statement.

      To circumvent the problem, remove the SOLUTION option from the RANDOM

      proc mixed satterthwaite kr df random solution s csh arh(1) toeph
