This is both a theoretical question and a stata technical one. I will
like to estimate the direct and indirect impact of an explanatory 'x'
variable on a dependent variable 'y'. 'X' is present in all the
equations of my system. The theoretical part of my question is whether
I can use non-standardized coefficients in order to get the direct and
indirect effect trough the necessary arithmetic calculation? If not, how
will I get a quick calculation of the standardized beta?...the option
beta does not work on reg3
Thanks!
Jon
