PROC HPLMIXED might produce incorrect standard errors for the fixed effects when all of the following conditions are met:
- The METHOD=ML option is specified in the PROC HPLMIXED statement.
- The NTHREADS= option is specified in the PERFORMANCE statement with a value of 2 or more.
- The estimated G matrix is nonsingular.
To circumvent this problem, specify NTHREADS=1 in the PERFORMANCE statement.
