[SEM] gsem, fvstandard -- Keep track of levels for factor variables


gsem ... [, fvstandard ...]


gsem, fvstandard, when set fvtrack factor is in effect, changes how gsem keeps track of factor-variable levels within interaction terms.


fvstandard specifies that all factor variables automatically be assigned a base level among the specified or implied levels and that implied yet unspecified elements of interaction terms be left in the model specification.

This option is ignored unless set fvtrack factor is in effect.
