Re-calibration of sample means
Published 22 Jun 2011 in stat.ME and stat.AP | (1106.4500v1)
Abstract: We consider the problem of calibration and the GREG method as suggested and studied in Deville and Sarndal (1992). We show that a GREG type estimator is typically not minimal variance unbiased estimator even asymptotically. We suggest a similar estimator which is unbiased but is asymptotically with a minimal variance.
