Sample surveys frequently experience the problem of non-response. Because of this, strategies for overcoming the obstacle every time it arises must be developed. In this paper, we suggest a new generalized ratio type estimator of population mean of main variable utilizing the kno...
A Publisher Correction to this article was published on 27 February 2023This article has been updatedAbstract Forest-going populations are key to malaria transmission in the Greater Mekong Sub-region (GMS) and are therefore targeted for elimination efforts. Estimating the size of this population is ...
This article developed an estimator for finite population mean under probability-proportional-to-size sampling in the presence of extreme values. Theoretical properties such as bias, variance, and consistency are derived. Monte Carlo simulations were performed to assess the consistency and efficiency of ...
Longitudinal sampling of the stool has yielded important insights into the ecological dynamics of the human gut microbiome. However, human stool samples are available approximately once per day, while commensal population doubling times are likely on the order of minutes-to-hours. Despite this mismatch...
This case control study evaluates the estimated vaccine effectiveness associated with 2, 3, or 4 doses of COVID-19 mRNA vaccination for protection against
Population growth in the world seems to raise the demand of water and food. However water resource is limited, which may arise water deficiency in several areas or countries. Particularly, agricultural water scarcity will accelerate the expansion of undernourishment damage caused by insufficient food ...
The dynamic urban system of Padang is constituted by a high concentration of population, Methods Based on the remote sensing and in situ data, we carry out a sequential procedure to estimate SBSTs. Fig. 3 gives a schematic overview from the data sets used, the chronology of the procedure ...
At each phase of population movement, every particle is attracted toward the following two ‘best’ values of problem solution. The first value, called i,best or pbest, is the best solution which has been achieved so far by the particle itself (the position giving the best cost value). ...
Although its population trajectory resulting from changes in these and related climate parameters is concerning, the species is readily amenable to restoration through out-planting. The goal of this study, therefore, was to evaluate relative climatic suitability of habitat for out-planting of silver...
