Added the new function exactmed_cat(), which
computes mediation effects when the mediator is categorical.
In exactmed_c() when used with case-control data,
the residual mean square error (MSE) has been replaced by the
weighted MSE as the estimator of the error variance (\(\sigma^2\)) of the mediator regression
model.
Documentation fixes and updates.
Added the new function exactmed_c(), which computes
mediation effects when the mediator is continuous.
The function exactmed() can now calculate mediation
effects with case-control data. The case-control functionality is also
available with the function exactmed_c().
Added print() methods for correct display of output
objects.
Documentation fixes and updates.
