Some research on calibration estimators at the National Agricultural Statistics Service
No government agency has been more influenced by the work of K.R.W. Brewer than the US National Agricultural Statistics Service (NASS). Kott and Bailey (ICES-II, 2000) described the then new sampling design (maximal Brewer selection) and estimator (based on Brewer’s cosmetic calibration) being adapted for the agency’s quarterly crops/stocks program. This paper will discuss more recent research at NASS on these and on another
Brewer suggestion, using instrumental variables in regression estimation.
