How Should Ecologists Define Sampling Effort? The Potential of Procrustes Analysis for Studying Variation in Community Composition
(2015-01-01)
Appropriate sampling effort is crucial for ecologists. Procrustes analysis can be used to tackle this question by quantifying the match between subsamples and the complete dataset. We used stream macroinvertebrates to show ...

Potential bias in multispecies sampling of purse seine catches
(Collective Volume of Scientifics Papers, 2009)
This paper discusses the various potential biases associated with species and size sampling carried out in the Atlantic Ocean during landings of purse seiners. This paper is a follow- up of the 4th Meeting of the WCPFC ...
Economic design of Shewhart control charts for monitoring autocorrelated data with skip sampling strategies
(Elsevier B.V., 2014-05-01)
On-line monitoring of process variability is strategic to achieve high standards of quality and maintain at acceptable levels the number of nonconforming items. Shewhart control charts are the simplest Statistical Process ...
An empirical examination of respondent driven sampling design effects among HIV risk groups from studies conducted around the world
(Springer, 2013)
For studies using respondent driven sampling (RDS), the current practice of collecting a sample twice as large as that used in simple random sampling (SRS) (i.e. design effect of 2.00) may not be sufficient. This paper ...
Sampling Strategies for Uncertainty Reduction in Categorical Random Fields: Formulation, Mathematical Analysis and Application to Multiple-Point Simulations
(Springer Verlag, 2019)
© 2019, International Association for Mathematical Geosciences.The task of optimal sampling for the statistical simulation of a discrete random field is addressed from the perspective of minimizing the posterior uncertainty ...
