MODEL CommandSeveral variables can be included on both sides of the WITH statement.In this situation, the variables on the left-hand side of the WITHstatement are crossed with the variables on the right-hand side of theWITH statement resulting in all possible combinations of left- and righthandside variables.The association between two categorical latent variables c1 and c2where c1 has three classes and c2 has four classes is specified asfollows:c1#1 c1#2 WITH c2#1 c2#2 c2#3;The statement above can be simplified to:c1 WITH c2;The association coefficient for the last class of each categorical latentvariable is fixed at zero as the default as in loglinear modeling.PWITHA second form of the WITH option is PWITH. PWITH pairs thevariables on the left-hand side of the PWITH statement with those on theright-hand side of the PWITH statement. For PWITH, the number ofvariables on the left-hand side of the PWITH statement must equal thenumber of variables on the right-hand side of the PWITH statement.
