Hi guys,
I am trying to measure effect size f2 for my model. However, my model is a bit confusing since it has one independent variable and two dependent variable
in this model X2 affects X3 and Y. So how I could calculate f^2 of X2? since the formulation is = R^2 include  R^2 Exclude/ 1  R^2 include.
Construct X2 contributes two R^2. One R^2 for X3 and R^2 for Y. So if I exclude X2, the amount of R^2 X3 and Y are changed. Can be seen from the model I attached.
Please advise me how to calculate f2 for this kind of model.
( this is not real my model and data..but the case is similar with this)
(ASK) calculate an Effect Size with a complex model

Dear Ananda,
The problem do you have is quickly resolved.
You calculate the effect size f^2 always for a specific connection in your path model. In your case that means you have to calculate the effect size of X2 on X3 and on Y also. Thereafter you have two effect sizes. There is not a effect size X2 for itself.
Best,
Christian
