Quantile selection in non-linear GMM quantile models
(Elsevier, 2020-07-16)
This note proposes a non-linear GMM quantile regression model to estimate the quantile as an additional parameter. The limiting distribution is studied. An empirical application to an intertemporal consumption model built ...
Integrating multiple data sources for assessing blue whale abundance and distribution in Chilean Northern Patagonia
(Wiley Blackwell Publishing, Inc, 2018-07-24)
Aim: Species distribution models are useful tools for depicting important habitat, assessing abundance and orienting conservation efforts. For small populations in poorly studied ecosystems, available data are often scarce ...
Aridity and grazing as convergent selective forces: An experiment with an Arid Chaco bunchgrass
(Ecological Society of America, 2010-10)
It has been proposed that aridity and grazing are convergent selective forces: each one selects for traits conferring resistance to both. However, this conceptual model has not yet been experimentally validated. The aim ...
Resources and soil influencing habitat selection by a subterranean rodent in a high cold desert
(Alliance Communications Group Division Allen Press, 2019-04)
Selection occurs when animals choose from among alternative habitat resources they find available in the environment. As selection is a hierarchical process, it can be studied at multiple spatial scales. Subterranean rodents ...
Analysis of a GPU implementation of Viola-Jones' Algorithm for Features Selection
(Universidad Nacional de La Plata. Facultad de Informática, 2017-12)
Faces and facial expressions recognition is an interesting topic for researchers in machine vision. Viola-Jones algorithm is the most spread algorithm for this task. Building a classification model for face recognition can ...
Land-use changes may explain the recent range expansion of the Black-shouldered Kite Elanus caeruleus in southern Europe
(Wiley Blackwell Publishing, Inc, 2008-10)
Occasional observations of Black-shouldered Kites Elanus caeruleus in Europe date back to the mid-19th century, but it was only recorded as a breeding species in the early 1960s in Portugal and a few years later in ...
