Efficient class of ratio cum median estimators for estimating the population median
PLoS ONE, 2023 In estimation theory, the use of auxiliary information significantly improves precision while estimating population parameters. In this paper, an efficient class of ratio cum median estimators of the population median is suggested using simple random ...

A Novel Sub-Type Mean Estimator for Ranked Set Sampling with Dual Auxiliary Variables
Journal of New Theory, 2023 This research introduces a novel sub-estimator designed to estimate the population mean under ranked set sampling, motivated by the new concept of a recently introduced sub-ratio estimator.

Bias of area counted from sub-pixel map: Origin and correction
Science of Remote Sensing, 2022 With the increasingly widespread use of sub-pixel mapping techniques in land cover/use mapping, more accurate area information is often required for a specific land cover type in a particular study region. However, the bias of area counted from sub-pixel

Dynamic Capital Structure Adjustment: Which estimator yields consistent and efficient estimates?
Journal of Economic and Financial Sciences, 2016 The partial adjustment model is key to a number of corporate finance research areas. The model is by its nature an autoregressive-distributed lag model that is characterised by heterogeneity among individuals and autocorrelation due to the presence of ...

An Investigation of Selection Bias in Estimating Racial Disparity in Stroke Risk Factors [PDF]
American Journal of Epidemiology, 2018 Selection due to survival or attrition might bias estimates of racial disparities in health, but few studies quantify the likely magnitude of such bias. In a large national cohort with moderate loss to follow-up, we contrasted racial differences in 2 stroke risk factors, incident hypertension and incident left ventricular hypertrophy, estimated by ...

A fixed count sampling estimator of stem density based on a survival function
Journal of Forest Science, 2015 In fixed count sampling (FCS) a fixed number (k) of observations is made at n randomly selected sample locations. For estimation of stem density, the distance from a random sample location to the k nearest trees was measured.
