The repeatability of measurement on the same occasion was evaluated by calculating the within-occasion coefficient of variation.
The within-occasion coefficient of variation was 7.25% and was calculated by using all accepted signals for all measurements (Table 2).
In such models, items on a scale are nested within occasions of measurement and occasions of measurement are nested within persons.
There were no differences between groups within occasions.
This objective function takes the form: (1),, and are the variances between subjects, between measurement occasions within each subject, and between quanta within occasions, respectively.
The two-level HLM model could be further generalized to a three-level model to account for items nested within occasions within persons.
Even though the application exemplified in the paper refers to subjects, measurement occasions within subjects, and measurement units within occasions, the generic results are applicable also to other sources of exposure variability that can be described by a hierarchical model.
Accordingly, averaging is made across quanta within each occasion, then across occasions within each subject, and finally across subjects.
Creativity within each occasion is spontaneous, the mark of actuality, and free, within the limits determined by its antecedent causes.
4) Within each occasion or database, the probability of capture does not differ between individuals.
