Causalmed mediator reference level

[pink_poodle]

What is the code to re-set mediator reference level in causalmed? I want to re-set "Mediator probability modeled" from 0 to 1. This does not work:

evaluate "_Default" _mediator = '1';

Many Thanks!

Check this example which shows how you can use the DESCENDING option on the CLASS statement.

Likewise you could also use the REF= for the individual variables.

Yes, it reads "Mediator probability modeled" is 1 now. The results table did not change. I guess it does not matter which one is the reference level for binary mediator.
