%description
The Directed Prediction Index ('DPI') is a quasi-causal inference (causal
discovery) method for observational data designed to quantify the relative
endogeneity (relative dependence) of outcome (Y) versus predictor (X)
variables in regression models. By comparing the proportion of variance
explained (R-squared) between the Y-as-outcome model and the X-as-outcome
model while controlling for a sufficient number of possible confounders,
it can suggest a plausible (admissible) direction of influence from a more
exogenous variable (X) to a more endogenous variable (Y). Methodological
details are provided at <https://psychbruce.github.io/DPI/>. This package
also provides functions for data simulation and network analysis
(correlation, partial correlation, and Bayesian networks).
