On local times, density estimation and supervised classification from functional data
(Elsevier Inc, 2011-01)
In this paper, we define a n-consistent nonparametric estimator for the marginal density function of an order one stationary process built up from a sample of i.i.d continuous time trajectories. Under mild conditions we ...
Nonparametric estimation of a surrogate density function in infinite-dimensional spaces
(Taylor & Francis Ltd, 2012-06)
A density function is generally not well defined in functional data context, but we can define a surrogate of a probability density, also called pseudo-density, when the small ball probability can be approximated by the ...
Comparing capture-recapture, mark-resight, and spatial mark-resight models for estimating puma densities via camera traps
(Alliance Communications Group Division Allen Press, 2014-04)
Camera-trapping surveys, in combination with traditional capture-recapture or spatially explicit capture-recapture techniques, have become popular for estimating the density of individually identifiable carnivores. When ...
Methods for assesing population size in sand dune lizards (Liolaemus multimaculatus)
(Herpetologists League, 2009-06)
Basic information, such as population size and density, is needed for conservation and management of many species, especially threatened species. Thus, well-designed population monitoring programs that use appropriate ...
Jaguar Panthera onca population decline in the Upper Paraná Atlantic Forest of Argentina and Brazil
(Cambridge University Press, 2008-10)
The Green Corridor of Argentina and Brazil is the largest forest remnant of the Upper Paraná Atlantic Forest. The jaguar population of this region is highly fragmented and reduced. To assess the status of the subpopulation ...
Maize stand density yield response of parental inbred lines and derived hybrids
(Crop Science Society of America, 2017-01)
Maize (Zea mays L.) grain yield has a parabolic response to stand density changes, creating an optimum stand density that maximizes yield. Argentinean commercial hybrids differ in their optimum stand density when grown at ...
The use of drones for conservation: A methodological tool to survey caimans nests density
(Elsevier, 2019-10)
The use of drones, or unmanned aerial vehicles (UAVs), is a burgeoning facet of conservation biology with the potential to revolutionize the way in which animals and habitats are monitored. Recently, the location and ...
Estimating detection and density of the Andean cat in the high Andes
(Alliance Communications Group Division Allen Press, 2011-02)
The Andean cat (Leopardus jacobita) is one of the most endangered, yet least known, felids. Although the Andean cat is considered at risk of extinction, rigorous quantitative population studies are lacking. Because physical ...
Estimation of geometrically necessary dislocation density from filtered EBSD data by a local linear adaptation of smoothing splines
(Wiley Blackwell Publishing, Inc, 2019-06)
An implementation of smoothing splines is proposed to reduce orientation noise in electron backscatter diffraction (EBSD) data, and subsequently estimate more accurate geometrically necessary dislocation (GND) densities. ...
On confidence bands for time series problems in the time and frequency domains
(Institute of Mathematical Statistics, 2003-12)
The construction of (asymptotic) simultaneous confidence bands for some time series problems is studied, typically for the sample autocorrelogram and windowed spectral density estimate. The following approaches are explored: ...
