Direct Effects from Estimated Model
indirect_overall(model, exper = NULL, t1 = 1, t2 = 2)
model |
An object of class multimedia containing the estimated mediation and outcome models whose mediation and outcome predictions we want to compare. |
exper |
An object of class multimedia_data containing the mediation and outcome data from which the direct effects are to be estimated. |
t1 |
The reference level of the treatment to be used when computing the indirect effect. |
t2 |
The alternative level of the treatment to be used when computing the indirect effect. |
Estimate direct effects associated with a multimedia model. These estimates are formed using Equation (10) of our preprint.
A data.frame summarizing the overall indirect effects associated with different settings of j in the equation above.
