Assessment of Non-Response under Ratio Method of Imputation in Two- Occasion Successive Sampling [PDF]

open access: yesJournal of Statistical Theory and Applications (JSTA), 2013
This paper considers the problem of estimation of the population mean of the study character under ratio method of imputation when some observations in the sample data are missing at random and the information on an auxiliary variable is readily ...

Using of Remote Sensing-Based Auxiliary Variables for Soil Moisture Scaling and Mapping

open access: yesRemote 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 ...

A New Family of Exponential Type Estimators in the Presence of Non-Response

open access: yesJournal of Mathematical and Fundamental Sciences, 2021
We propose families of estimators for the population mean using an exponential function in case of non-response. This situation is examined under two cases, Case I and II. The bias, MSE and minimum MSE are separately obtained for both cases.

Auxiliary Variables in TLA+

open access: yesCoRR, 2017
Auxiliary variables are often needed for verifying that an implementation is correct with respect to a higher-level specification. They augment the formal description of the implementation without changing its semantics--that is, the set of behaviors that it describes.

A simulation study: new optimal estimators for population mean by using dual auxiliary information in stratified random sampling

open access: yesJournal of Taibah University for Science, 2020
Recently, Haq et al. [A new estimator of finite population mean based on the dual use of the auxiliary information. Commun Stat Theory Methods. 2017;46(9):4425–4436] utilized the dual auxiliary information under simple random sampling only.

Improved Estimators for Estimating Average Yield Using Auxiliary Variable [PDF]

open access: yesInternational Journal of Mathematical, Engineering and Management Sciences, 2019
In this paper, we consider the improved estimation of average production of peppermint at block level of Barabanki district of Uttar Pradesh State (India). We suggest certain estimators for population-mean.

Restructured searls family of estimators of population mean in the presence of nonresponse

open access: yesFrontiers in Applied Mathematics and Statistics, 2022
Nonresponse is a major problem encountered by surveyors when conducting sampling surveys. The present study suggested a naïve modified Searls method for the elevated estimation of the population mean of the primary variable under investigation by ...

A geoadditive Bayesian latent variable model for Poisson indicators [PDF]

open access: yes, 2006
We introduce a new latent variable model with count variable indicators, where usual linear parametric effects of covariates, nonparametric effects of continuous covariates and spatial effects on the continuous latent variables are modelled through a ...

Auxiliary Variable Based Particle Filters [PDF]

open access: yes, 2001
We model a time series {y t , t = 1, ..., n} using a state-space framework with the {y t |α t } being independent and with the state {α t } assumed to be Markovian. The task will be to use simulation to estimate f(α t |F t ), t = 1, ..., n, where F t is contemporaneously available information.

A new exponential estimator for finite population mean under double sampling using one auxiliary variable [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2019
This paper proposes an exponential estimator of a population mean under double sampling using one auxiliary variable. The proposed estimator is modified from the estimator of Khatua and Misha (2013) and Ozgul and Cingi (2014).
