DOI: 10.1109/lsp.2025.3550280
Abstract: Modern high-dimensional datasets are often formed by acquiring samples from multiple sources having heterogeneous quality, i.e., some sources are noisier than others. Collecting data in this manner raises the following natural question: what is the… read more here.

DOI: 10.1371/journal.pone.0307710
Abstract: Background Generalizability theory is widely used in psychological and educational measurement. Budget and cost are the problems that cannot be neglected in the measurement. When there is a budget constraint, the generalizability theory needs to… read more here.

DOI: 10.3390/land14030545
Abstract: The transition from conventional soil mapping (CSM) to digital soil mapping (DSM) not only affects the final map products, but it also affects the concepts of scale, resolution, and sampling intensity. This is critical because… read more here.

Optimal sample sizes and statistical decision rules
Sign Up to like & getrecommendations! Published in 2024 at "Theoretical Economics"
DOI: 10.3982/te4840
Abstract: A statistical decision rule is a mapping from data to actions induced by statistical inference on the data. We characterize these rules for data that are chosen strategically in persuasion environments. A designer wishes to… read more here.
