SN-005132 ***Alert Note***
PROC MIXED May Report Wrong Satterthwaite or KR Degrees of Freedom with
Heterogeneous Covariance Structures on the RANDOM statement
Product: SAS/STAT
Component: MIXED procedure
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
statement.
