Dear all,
I have a model to estimate direct and indirect effects among X, Y1, and Y2.
Y1 = F( X, A, B)
Y2 = F( Y1, X, G)
X and Y2 are binary variables and Y1 is a continuous variable.
The direction of effects is unidirectional from X to Y1 and from Y1 to Y2.
I would like to find out the X's effects on Y1 and Y2 and also Y1's
effect on Y2 simultaneously.
But, I'm wondering how to estimate the model with Y2 and to estimate
two models simultaneously in STATA.
Can anyone point let me know how to deal this model in STATA?
Thank you in advances.
Charlie.
