Optimum strata boundaries and sample sizes in health surveys using auxiliary variables. [PDF]
PLoS ONE, 2018 Using convenient stratification criteria such as geographical regions or other natural conditions like age, gender, etc., is not beneficial in order to maximize the precision of the estimates of variables of interest.

Improving inference of Gaussian mixtures using auxiliary variables [PDF]
Statistical Analysis and Data Mining: The ASA Data Science Journal, 2015 AbstractExpanding a lower‐dimensional problem to a higher‐dimensional space and then projecting back is often beneficial. This article rigorously investigates this perspective in the context of finite mixture models, specifically how to improve inference for mixture models by using auxiliary variables. Despite the large literature in mixture models and

A class of ratio estimators of a finite population mean using two auxiliary variables. [PDF]
PLoS ONE, 2014 In sample surveys, it is usual to increase the efficiency of the estimators by the use of the auxiliary information. We propose a class of ratio estimators of a finite population mean using two auxiliary variables and obtain mean square error (MSE ...

An Auxiliary Variable Method for Markov Chain Monte Carlo Algorithms in High Dimension [PDF]
Entropy, 2018 In this paper, we are interested in Bayesian inverse problems where either the data fidelity term or the prior distribution is Gaussian or driven from a hierarchical Gaussian model.

Using of Remote Sensing-Based Auxiliary Variables for Soil Moisture Scaling and Mapping [PDF]
Remote Sensing, 2022 Soil moisture is one of the core hydrological and climate variables that crucially influences water and energy budgets. The spatial resolution of available soil moisture products is generally coarser than 25 km, which limits their hydro-meteorological ...

Median estimation using auxiliary variables
, 2012 In the present study the estimation of the median has been taken into consideration using different methods of analysis. First of all the estimation of the median without auxiliary information is analyzed. Then the method of Kuk and Mak proposed in 1989 is exposed: this way of estimating the median is based on the knowledge of the population median of ...
