Problem Note 11542: Incorrect Covariance Parameter Estimates When LOCAL Option Used with
Kronecker Product Structures on REPEATED Statement
The covariance parameters for the second effect in a Kronecker-product
covariance structure will be incorrect if the LOCAL option is added to
the REPEATED statement and the NOPROFILE option is not included on the
PROC MIXED statement.
To circumvent the problem, add the NOPROFILE option to the PROC MIXED
statement, or download the available hotfix corresponding to the SAS
Release you are running.
