An implementation of instrumental variables regression using
two-stage least-squares (2SLS) estimation, based on the
ivreg() function previously in the AER package. In
addition to standard regression functionality (parameter estimation,
inference, predictions, etc.) the package provides various regression
diagnostics, including hat values, deletion diagnostics such as
studentized residuals and Cook’s distances; graphical diagnostics such
as component-plus-residual plots and added-variable plots; and effect
plots with partial residuals.
