Ratio Estimator in Adaptive Cluster Sampling without Replacement of Networks
, 2014 In this paper, we study the estimators of the population total in adaptive cluster sampling by using the information of the auxiliary variable. The numerical examples showed that the ratio estimator in adaptive cluster sampling without replacement of ...

A new exponential ratio-type estimator with linear combination of two auxiliary variables. [PDF]
PLoS ONE, 2014 In sample surveys, it is usual to make use of auxiliary information to increase the precision of estimators. We propose a new exponential ratio-type estimator of a finite population mean using linear combination of two auxiliary variables and obtain mean

Non-Data-Aided Parameter Estimation in an Additive White Gaussian Noise Channel
, 2005 Non-data-aided (NDA) parameter estimation is considered for binary-phase-shift-keying transmission in an additive white Gaussian noise channel. Cramer-Rao lower bounds (CRLBs) for signal amplitude, noise variance, channel reliability constant and bit ...

Data Science Journal, 2010 An alternative ratio-cum-product estimator of population mean using the coefficient of kurtosis for two auxiliary variates has been proposed. The proposed estimator has been compared with a simple mean estimator, the usual ratio estimator, a product ...

An Unbiased Estimator of Finite Population Mean Using Auxiliary Information
Journal of Statistical Theory and Applications (JSTA), 2021 In this paper, an unbiased estimator is constructed by using a linear combination of an estimator of study variable and mean per unit estimator of an auxiliary variable under simple random sampling without replacement scheme.

ESTIMATING THE HEDGE RATIOS [PDF]
CBU International Conference Proceedings, 2016 This paper examines the problem of hedging portfolio returns. Many practitioners and academicians endeavor to solve the problem of how to calculate the optimal hedge ratio accurately. In this paper we compare estimates of the hedge ratio from a classical approach of a linear quantile regression, based on selected quantiles as medians, with that of a ...
