  • More than thirty years ago Halbert White inaugurated a "model-robust" form of statistical inference based on the "sandwich estimator" of standard error. This estimator is known to be "heteroskedasticity-consistent", but it is less well-known to be "nonlinearity-consistent" as well. Nonlinearity, however, raises fundamental issues because regressors are no longer ancillary, hence can't be treated as fixed. The consequences are severe: (1)~the regressor distribution affects the slope parameters… CONTINUE READING
