Estimating population abundance using counts from an auxiliary population
Environmental and Ecological Statistics - Tập 27 - Trang 509-526 - 2020
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......
Correction: Nonparametric conditional density estimation in a deep learning framework for short-term forecasting

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
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......
Upper level set scan statistic for detecting arbitrarily shaped hotspots
Environmental and Ecological Statistics - Tập 11 - Trang 183-197 - 2004
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......
Accounting for multiple testing in the analysis of spatio-temporal environmental data
Environmental and Ecological Statistics - Tập 27 - Trang 293-318 - 2020
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......
Species abundance estimation using point-to-plant sampling in a design-based setting
Environmental and Ecological Statistics - Tập 9 - Trang 393-403 - 2002
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......
Recursive residuals and model diagnostics for normal and non-normal state space models
Environmental and Ecological Statistics - Tập 3 Số 4 - Trang 291-309 - 1996
A history matching approach for calibrating hydrological models
Environmental and Ecological Statistics - Tập 26 - Trang 87-105 - 2019
Calibration of hydrological time-series models is a challenging task since these models give a wide spectrum of output series and calibration procedures require significant amount of time. From a statistical standpoint, this model parameter estimation problem simplifies to finding an inverse solution of a computer model that generates pre-specified time-series output (i.e., realistic output series......
Economic analysis of nature preservation investments: the zonal travel cost approach applied for Harghita County of Romania
Environmental and Ecological Statistics - Tập 21 - Trang 83-93 - 2013
The paper is focused on the cost of travel method and specific issues involved by the use of this method for monetization of benefits provided by nature preservation investment projects. Usually, nature preservation investment projects are non revenue generator projects and consequently the monetization of benefits provided is essential in the process of analysis and valuation of these projects, b......
