Hi , I got one mediator variable that has three levels, such as "difficult" , "medium" and "easy", I know CAUSALMED can handle binary or continuous mediators, however I am not sure if I can include two binary mediators in the model by creating two dummy variables for "medium" and "easy"?

 

Is there any way I can apply this three level categorical mediator?

 

Thanks,

 

Robin

The methodology that CAUSALMED employs does not allow for more than one mediator. However, see the second example in this note

Thanks for reply. The example involve two mediators, but I noticed that it does not include bootstrapping as Causalmed, how could I include bootstrapping in this method?
