Sample selection bias and presence-only distribution models: implications for background and pseudo-absence data.
Most methods for modeling species distributions from occurrence records require additional data representing the range of environmental conditions in the modeled region. These data, called background or pseudo-absence data, are usually drawn at random from the entire region, whereas occurrence collection is often spatially biased toward easily accessed areas. Since the spatial bias generally re...
متن کاملNondetection sampling bias in marked presence-only data
Species distribution models (SDM) are tools used to determine environmental features that influence the geographic distribution of species' abundance and have been used to analyze presence-only records. Analysis of presence-only records may require correction for nondetection sampling bias to yield reliable conclusions. In addition, individuals of some species of animals may be highly aggregate...
متن کاملLogistic methods for resource selection functions and presence-only species distribution models
In order to better protect and conserve biodiversity, ecologists are making increasing use of machine learning and statistical modeling to understand how species respond to their environment and to predict how they will respond to future climate change, habitat loss and other threats. A fundamental modeling task is to estimate the conditional probability that a given species is present in (or u...

متن کاملSampling bias and logistic models
In a regression model, the joint distribution for each finite sample of units is determined by a function px.y/ depending only on the list of covariate values xD .x.u1/,. . .,x.un// on the sampled units. No random sampling of units is involved. In biological work, random sampling is frequently unavoidable, in which case the joint distribution p.y,x/ depends on the sampling scheme. Regression mo...
