This variable constituted a proxy for disease stage because patients that only had medical management were likely to be the least ill, but those that entered a study and then had PTCA or CABG were probably at a more advanced stage of disease upon presentation.
This latent class variable constitutes the measure of insomnia symptoms used in this study and represents an individual's pattern of symptoms across the 20 year study period rather than at any single point in time.
Each variable constitutes a constant function along with its own past values.
E.g., for the comparative correlation between frontal lobe size and basal ganglia size, the independent variable constitutes the residuals of a regression of frontal lobe size to brain minus frontal lobe and basal ganglia size, the dependent variable comprises the residuals of a regression of basal ganglia size to brain minus frontal lobe and basal ganglia size.
The most studied definition of workplace-related stress has been the job-demand-control (JDC) model. 2 According to Karasek, the job demand variable constitutes volume and intensity of workload and job control referred to the working individual's potential control over pace and content of their tasks.
As these variables constitute elements of the criteria for MES this result was expected and therefore the associations are not particularly clinically relevant.
Taken together, all three of these variables constitute the institutional environment for the purpose of this analysis.
It is assumed that wild foods are used as, both observed variable constituting the IFA and, latent variable measured from different sources.
The DOP content of the Everglades water matrix was characteristically variable constituting 4 56% of total phosphorus (TP) and demonstrated no correlation with dissolved organic carbon (DOC).
Moreover, the choices of all degrees of freedom of the design, associated with the variables constituting the model, their fuzzy partitions, the rule base construction, and the inference process, are suggested in this paper.
Macroscopic variables such as speed, flow and density have been used in assessing the performance of pedestrian facilities and these variables constitute the Fundamental Diagrams (FDs) of pedestrian flow.
