The phrase "absence data and" is not correct in written English as it appears to be incomplete.
It may be intended to refer to data related to absence but lacks clarity and context.
Example: "The absence data and attendance records will be reviewed for accuracy."
Alternatives: "absence information and" or "absence records and".
We compared performance of two binomial models Classification and Regression Trees (CART) and Generalised Additive Models (GAM)—with Maximum Entropy (MAXENT) models developed from (i) presence records and available absence data and (ii) developed using presence records and background data.
The results show that MaxEnt with pseudo absence data and SVM with background absence have highest area of understory coffee presence prediction with 12.2% and 23.1% area coverage of indigenous forest, respectively.
These range from issues with the accuracy of species presences, the lack of reliable absence data and the limited spatial resolution of environmental factors known or thought to control deep-sea species' distributions.
We piloted methods for collecting sickness absence data and data for economic evaluation and found this was feasible.
Further studies are needed to validate the LEAPS against external and objective measures of work performance, such as employer work absence data and objective measures of productivity.
36 Strengths of the trial included good recruitment and retention, complete questionnaire and sickness absence data and complementary qualitative and economic analyses.
Despite a lack of significant differences in community richness among sites with different R. fistulosa infestation levels, there were significant differences in community composition, both when estimated from presence-absence data and from relative abundance data, after controlling statistically for geographic proximity among sites.
Analyses of MNTD using either abundance weighted or presence-absence data and analyses of MPD using abundance data did not indicate consistent differences between the three site types, but do point to important differences between sites in phylogenetic composition of bee communities.
Biological data from each site were transformed to presence-absence data and a similarity matrix was constructed based on the taxonomic dissimilarity coefficient Theta defined by Clarke and Warwick [49] and Clarke et al. [50].
Distribution models characterize dimensions, generally mean climatic variables, of the current realized niche of a species based on presence-absence data and then use future climate forecasts to project changes in the distribution of suitable habitat for a species.
Taken together with examination of injury and sickness absence data, interviews and field observations, and biomechanical computer modelling, the measurement programme confirmed the potential risks.
