Description: 
    The Directed Prediction Index ('DPI') is
    a simulation-based 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).
