Multiplicative Interaction Models Diagnostics and Visualization
Description
Producing Flexible Marginal Effect Estimates with Multiplicative Interaction Models
Details
This package performs diagnostics and visualizations of multiplicative interaction models. Besides conventional linear interaction models, it provides two additional estimation strategies–linear regression based on pre-specified bins and locally linear regressions based on Gaussian kernels–to flexibly estimate the conditional marginal effect of a treatment variable on an outcome variable across different values of a moderating variable. These approaches relax the linear interaction effect assumption and safeguard against excessive extrapolation.
