Finally, the union variables have a similar effect on the firm component of the inter‐industry differential but have, now, virtually no effect on the person component.
The person component of the differentials is mostly related to skills of the workforce, be it education or the lack thereof.
As explained in the analytical strategy, the four health-related variables are included as a between-person component, the person-specific mean (m), and a within-person component, the deviation from the person-specific mean (d).
The PE fit model is composed of two interactive components: the person component and the environment component.
In this model, the person component is defined as a set of competencies, including biological health, cognitive function, and sensory and motor skills.
We have not presented the estimates for the "within person" component for sleep and the other measures as they were small and not significant.
In the hybrid approach each time-varying predictor variable is decomposed into a between-person component (included in the analyses as the person-specific mean, denoted with 'm') and a within-person component (included in the analyses as a deviation from the person-specific mean, with positive scores indicating a decline over time, denoted with 'd'd.
Variability in benzene concentrations was remarkable, with 95% of the estimated values falling within a 274-fold range, and was comprised entirely of the within-person component of variance (representing exposures of the same subject at different times of refueling).
The within-person component is large for all four sections, and the low ICCs suggest that the loading is more dependent on factors related to changing conditions in the environment than on traits specific to the individuals being monitored.
