An Inverse-Occurrence Sampling Approach for Urban Flood Susceptibility Mapping
Data-driven flood susceptibility modeling is an efficient way to map the spatial distribution of flood likelihood. The quality of the flood susceptibility model relies on the learning technique and the data used for learning.

Resolving the Raven Paradox: Simple Random Sampling, Stratified Random Sampling, and Inference to the Best Explanation [PDF]
Simple random sampling resolutions of the raven paradox relevantly diverge from scientific practice. We develop a stratified random sampling model, yielding a better fit and apparently rehabilitating simple random sampling as a legitimate idealization.

Sampling of cashew nuts as an aid to research for the genetic improvement of cashew tree [PDF]
: The objective of this work was to estimate sample sizes of cashew (Anacardium occidentale) nuts as an aid to the genetic improvement of cashew tree. Nuts were separated by size: nuts < 17 mm were classified as size 1 (S1); 17 mm ≤ nuts < 19 mm, size 2 (

AREA ESTIMATION OF MULTI-TEMPORAL GLOBAL IMPERVIOUS LAND COVER BASED ON STRATIFIED RANDOM SAMPLING [PDF]
Estimating area of impervious land cover is the most useful and one of the ecological assessment indexes of urban and regional environment. Global land cover maps are inevitably misclassified, which affects the quality and application of the data ...

Comparison of quota sampling and stratified random sampling [PDF]
The possibility that researchers should be able to obtain data from all cases is questionable. There is a need; therefore, this article provides a probability and non-probability sampling. In this paper we studied the differences and similarities of the two with approach that is more of fritter away time, cost sufficient with energy required ...
