Sentence examples for models to apportion from inspiring English sources

Some investigators have attempted to use physical or statistical models to apportion the total PM exposure to individual sources, but these techniques often lead to large uncertainties in the actual magnitude of the exposure.

23 Whereas Howie and colleagues described the variation within a sample of Scottish practices in respect of doctors' communication, 30 several other studies have used hierarchical models to apportion the sources of variance in patients' feedback in primary care settings.

Considering Ottman's five models of interactions, the first of these two conditions will only hold for models D and E. Thus, in the absence of detailed knowledge of biological mechanisms of disease and the roles of environmental exposures and gene polymorphisms, it will generally be inadvisable to use standard statistical models to apportion variance in evaluating gene-environment interactions.

Emission source chemical fingerprints including stable isotopes and PAHs have been successfully used in receptor modelling to apportion elemental concentrations measured in terrestrial receptors back to source type.

Against this background, we aimed to quantify the decline in CHD mortality between 2000 and 2010 in Scotland and then use the IMPACTSEC model to apportion this mortality decline to treatments and changes in risk factors across socioeconomic fifths.

Design Retrospective analysis using IMPACTSEC, a previously validated policy model, to apportion the recent decline in coronary heart disease mortality to changes in major cardiovascular risk factors and to increases in more than 40 treatments in nine non-overlapping groups of patients.

The study provided a timely opportunity to assess the performance of both local and global (genetic algorithm; GA) optimisation techniques in the sediment geochemistry mass balance modelling used to apportion sources.

Other studies have used the receptor modeling approach to apportion sources of central-site PM2.5 to represent the average population exposure (Laden et al. 2000; Mar et al. 2000; Tsai et al. 2000).

Two models were used to apportion human cases to sources on the basis of sequence types: the modified Hald model and the Island model (12, 15).

Statistical modeling was used to apportion human cases to potential disease sources, thereby estimating each source's relative importance (13 , 15 16).

Because these two parts are directly interpretable in terms of economic models, it is important to apportion the inter‐industry differentials into these person and employer parts.
