## 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
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.
## Background: The ratio of two measured fluorescence signals (called x and y) is used in different applications in fluorescence microscopy. Multiple instances of both signals can be combined in different ways to construct different ratio estimators. Methods: The mean and variance of three estimato
