gformula mediation

[Guest]

Hi everyone
I need to define a particular scenario constrast in gformula mediation:
I need to compare the current level of exposure with reducing the exposure from its current state by 1 standard deviation for everyone. (I have a continous variable).
Do you how i can do it? i usually use "baseline" and "alternative" in the code to define the two comparing scenarios, but i can't figure out how define the particular scenarios mentioned above.

Many thanks

I doubt anybody will be able to answer this question without more information about the data you have. I suggest that you post a small but representative sample of your data, using the -dataex- command to do so. (-dataex- is part of your regular Stata installation, unless you are using a very ancient version. In the latter case, -ssc install dataex- will get it for you. Read the help fie for details if you are not familiar with using it.)

Be sure also to explain what each of the variables you post is/means in a way that relates to the problem you are seeking help for.
