The estimator used to calculate incremental cost-effectiveness (C/E) ratios from sampled data is biased but consistent. While the bias may be negligible in studies with large sample sizes, it is potentially important in analyses based on small samples. When patient-level data on costs and effects ar
This paper proposes a method for using multi-auxiliary information at both the design and the estimation stages of a sample survey. The proposed method is an extension of the clessical multivariate method of OLKIN (1968). The resulte of AQARWAL and KUMAR (1978) come out aa a special case.
## Abstract A class of almost unbiased ratio estimators for population mean ฯ is derived by weighting sample ฯ = (1/__n__) ฯ __y__~__i__~, ratio estimators ฯ and an estimator, ฯ (__y__~__i__~/__x__~__i__~). It is shown that NIETO DE PASCUAL (1961) estimator is a particular member of the class and a
