Thank you very much Yves! I have managed to get the total indirect effects that i wanted but it seems to only work on the unstandardized coefficients. I use "standardized =TRUE" in the "summary" command but the "std.all" column has the same values as the "Estimate" (unstandardized) column for the new parameters defined by the ":=" operator. All other parameters i.e. using "~" have been standardized.
How do i go about calculating the indirect effects based on standardized coefficients?
