What I do not understand yet is why we need a package like multimed if we can decompose a model with two causally dependent mediators (infant deprivation --> education level --> economic position --> aging well) into two models (infant deprivation --> education level --> aging well & education level --> economic position --> aging well).<BR>
<BR>
Following your advise, I should include infant deprivation as a confounder in the model education level --> economic position --> aging well. But if deprivation conditions education strongly, I could end not finding any direct nor indirect effect of education on aging well.<BR>

Hi,<BR>
<BR>
In the model (education level --> economic position --> aging well) you should include all the variables that potentially confound the association between education level and economic position, education level and ageing well, and economic position and ageing well. <BR>
<BR>
