Estimating population abundance using counts from an auxiliary population
Environmental and Ecological Statistics - Tập 27 - Trang 509-526 - 2020
Matthew R. P. Parker, Vivian Pattison, Laura L. E. Cowen
We develop a new method for estimating population abundance for notoriously difficult to count populations. This is made possible using an easy to count auxiliary population with a known link to the target population under the framework of a layered hidden Markov model. We apply the new methods to estimate the breeding population of an Ancient Murrelet seabird colony, using Ancient Murrelet chicks... hiện toàn bộ

How to tackle plastic bags and bottles pollution crisis in Pakistan? A cost–benefit analysis approach
Environmental and Ecological Statistics - Tập 28 - Trang 697-727 - 2021
Yousaf Ali, Sundas Sara, Obaid ur Rehman
Plastic pollution is among the many socio-economic and environmental dilemmas that have engulfed Pakistan. The exponentially increasing consumption of plastic and the difficulty of dealing with its waste has compelled the government to impose a ban on the use of non-biodegradable plastics. This ban has made Pakistan the 128th country to curb plastic usage through punitive measures. However, the co... hiện toàn bộ
A fuzzy goal programming with interval target model and its application to the decision problem of renewable energy planning
Environmental and Ecological Statistics - Tập 27 - Trang 527-547 - 2020
Amin Hocine, Mohammed Seghir Guellil, Eyup Dogan, Samir Ghouali, Noureddine Kouaissah
Optimizing sustainable renewable energy portfolios is one of the most complicated decision making problems in energy policy planning. This process involves meeting the decision maker’s preferences, which can be uncertain, while considering several conflicting criteria, such as environmental, societal, and economic impact. In this paper, rather than using existing techniques, a novel multi-objectiv... hiện toàn bộ
Upper level set scan statistic for detecting arbitrarily shaped hotspots
Environmental and Ecological Statistics - Tập 11 - Trang 183-197 - 2004
G. P. Patil, C. Taillie
A declared need is around for geoinformatic surveillance statistical science and software infrastructure for spatial and spatiotemporal hotspot detection. Hotspot means something unusual, anomaly, aberration, outbreak, elevated cluster, critical resource area, etc. The declared need may be for monitoring, etiology, management, or early warning. The responsible factors may be natural, accidental, o... hiện toàn bộ
Accounting for multiple testing in the analysis of spatio-temporal environmental data
Environmental and Ecological Statistics - Tập 27 - Trang 293-318 - 2020
José Cortés, Miguel Mahecha, Markus Reichstein, Alexander Brenning
The statistical analysis of environmental data from remote sensing and Earth system simulations often entails the analysis of gridded spatio-temporal data, with a hypothesis test being performed for each grid cell. When the whole image or a set of grid cells are analyzed for a global effect, the problem of multiple testing arises. When no global effect is present, we expect $$ \alpha $$% of all gr... hiện toàn bộ

Species abundance estimation using point-to-plant sampling in a design-based setting
Environmental and Ecological Statistics - Tập 9 - Trang 393-403 - 2002
Lucio Barabesi, Marzia Marcheselli
A new species abundance estimator is proposed when point-to-plant sampling is adopted in a design-based framework. The method is based on the relationship between each species abundance and the probability density function of the relative squared point-to-plant distance. Using this result, a kernel estimator for species abundance is provided and the nearest neighbor method is suggested for bandwid... hiện toàn bộ
Scale invariant measures of pattern intensity and grain: A simulation experiment
Environmental and Ecological Statistics - Tập 7 - Trang 255-261 - 2000
Ladislav Mucina, Ju¨rgen Geißelbrecht, Leonore Geißelbrecht-Taferner
We propose new dimensionless and scale-invariant measures for detection of pattern intensity, defined as the level of aggregation of individuals regardless their kind, and pattern grain, the level of segregation among individuals of at least two different kinds in point-pattern spatial data using tessellation methodology. Both real and simulated data on spatial distribution of plants in ecological... hiện toàn bộ
