%description
The Directed Prediction Index ('DPI') is a simulation-based and
conservative method for quantifying the relative endogeneity (relative
dependence) of outcome (Y) versus predictor (X) variables in multiple
linear 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 potential confounding
variables, it suggests a more plausible influence direction from a more
exogenous variable (X) to a more endogenous variable (Y). Methodological
details are provided at <https://psychbruce.github.io/DPI/>.
