Multivariate Multi-Objective Allocation in Stratified Random Sampling: A Game Theoretic Approach. [PDF]
PLoS ONE, 2016 We consider the problem of multivariate multi-objective allocation where no or limited information is available within the stratum variance. Results show that a game theoretic approach (based on weighted goal programming) can be applied to sample size ...

Exploring mixture estimators in stratified random sampling. [PDF]
PLoS OneAdvancements in sensor technology have brought a revolution in data generation. Therefore, the study variable and several linearly related auxiliary variables are recorded due to cost-effectiveness and ease of recording. These auxiliary variables are commonly observed as quantitative and qualitative (attributes) variables and are jointly used to ...

Multi-line characterization of whole molecular clouds using stratified random sampling [PDF]
EPJ Web of Conferences, 2022 We have developed a new technique to characterize the multi-line emission from molecular clouds using statistical sampling. Our method uses available extinction maps to select a relatively small sample of cloud positions that cover the full range of ...
