add_index {JSmediation}

Adds an indirect effect index to a fitted mediation model

Description

add_index is a generic function that adds a (moderated) indirect effect index to an object created with an ⁠mdt_*⁠ family function. This index is computed using Monte Carlo methods. This function invokes particular methods depending of the class of the mediation model. For example, with a model fitted with mdt_simple, add_index will invoke add_index.simple_mediation.

Usage

add_index(mediation_model, times = 5000, level = 0.05, ...)

Arguments

mediation_model

A mediation model fitted with an ⁠mdt_*⁠ family function.

times

Number of simulations to use to compute the Monte Carlo index's confidence interval.

level

Alpha threshold to use for the confidence interval.

...

Further arguments to be passed to specific methods.

Value

An object of the same class as mediation_model, but with index added for later use.
