The following features are now production:

• METHOD=FIML option

• mean structure analysis with the COSAN model

• extended PATH modeling language that supports the specification of variances or covariances as paths

• unnamed free parameter specification in all model types

• improved RAM model specification

In addition, PROC CALIS now provides detailed analysis of the missing patterns with the FIML estimation method. With the COVPATTERN= and MEANPATTERN= options, you can specify various standard mean and covariance patterns by using keywords. PROC CALIS then generates the required covariance and mean structures automatically.
