%description
A collection of tests to analyze the causal direction of dependence in
linear models (Wiedermann, W., & von Eye, A., 2025, ISBN: 9781009381390).
The package includes functions to perform Direction Dependence Analysis
for variable distributions, residual distributions, and independence
properties of predictors and residuals in competing causal models. In
addition, the package contains functions to test the causal direction of
dependence in conditional models (i.e., models with interaction terms) For
more information see <https://www.ddaproject.com>.
