Each individual was assigned estimated monthly average contaminant concentrations in the drinking water system serving the individual's residence during the period of residence.
Each plant had one department for which the exposure level could not be estimated but we believed to be low; for these departments, we used the lowest assigned estimate for the pertinent time period at that facility.
The sequence positions of the remaining 13 markers, for which a definitive megaBLAST-based location could not be identified within the expected genomic location, were assigned estimated positions based on their proximity to flanking markers on the genetic linkage map.
Using a high spatially resolved dispersion model to assess home outdoor NO2 and PM10 exposure, we showed for the first time that the geocoding techniques used to individually assign estimates of long-term exposure may have an impact on the estimated associations with lung function.
Christa Dickey, a spokeswoman for the American College of Sports Medicine, which publishes such a chart, cautions that figuring out calories "is always a bit of a challenge since you can really only assign estimates".
Experts' opinions informed the parameterization of the remaining variables by assigning estimates of average, maximum, and minimum values for each variable.
In each case, a unique typology of land cover and aquatic resources was developed and relevant economic valuation studies were queried in order to assign estimates of ecosystem service values to each category in the typology.
One is to assign estimated cost directly to a related task, the other is to assign resources like equipment, material, and labor to a related activity.
The coefficients derived from this pooled regression allow us to assign estimated effects to each of the models considered above: an intention effect, a distributional effect, and a control effect (Table 1).
Third, we applied land-use regression models to assign estimated NO2 and soot concentrations from traffic-related sources to the residential address of each individual (Brauer et al. 2003; Hochadel et al. 2006).
