The MICr package provides the ability to compute and display Matrices of Implied Causation (MICs) and the corresponding MIC Tables for Structural Equation Models (SEMs).
MICs provide an at-a-glance way to examine the causal implications of a model. The MIC and MIC Table display the total effects, adding up all mediated and direct effects, of every variable on every other variable in the model. We argue that model-implied causal structures should be examined as a means of model checking, and that MIC comparisons should be used as part of model comparison and utilized as a form of intervention design.
You can install the latest version of MICr with:
# install.packages("devtools")
devtools::install_github("trbrick/MICr")
