I test a structure equation model of five variables 2 of them independent and 2 moderate and one is dependent.
the relationships in mplus are
D by d1 d2;
R by r1 r2;
A by a1 - a4;
M by m1 m2;
S by s1 - s3;
A on R D S
S on M R
R on M
the question is:
How can I do the interaction effect between D and R on the Dependent Variable A??
