Omit, Substitute and Backsolve

You can specify the model condensation in the TAB file, instead of in a separate STI file. Examples:

OMIT a1 a1oct a1mar a1_s a2 a2mar ;

BACKSOLVE p1lab USING E_p1lab ;

SUBSTITUTE p1 USING E_Price1 ;

To substitute out a Levels variable X, use the name of the associated linear variable(c_X for ordinary change, p_X for percentage change):

VARIABLE (CHANGE,LEVELS) XYZ ;

OMIT c_XYZ ;

VARIABLE (LEVELS) X ;

EQUATION(LEVELS) Eqn_HOUSE A*X + B*Y = C ;

SUBSTITUTE p_X USING Eqn_HOUSE ;
