Aggregation
Token A number assigned to an outside link by the border nodes at the ends of the outside link. The same number is associated with all uplinks and induced uplinks associated with the outside link. In the parent and all higher-level peer group, all uplinks with the same aggregation token are aggregated.

Aggregation
Combining index relatives from one level to the next higher level. The procedure for the International Price Program begins with the aggregation of item level relatives to weight group relatives. The weight group relatives are then aggregated to the classification group relatives. The classification group relatives are then aggregated to the stratum lower relatives which in turn are aggregated up the tree of stratum upper relatives to the All Import or All Export index level.

Aggregation
May refer to 'schooling', which involves behavioural grouping of animals; but 'aggregation' is also used to reflect concentration (of fish) for unknown reasons or direct causes such as the concentration of food organisms, or for spawning. Comonwealth of Australia (1997)

Aggregation
A process by which the properties of a collection are described in terms of the sums of the properties of the units contained in that collection. The most elementary aggregative procedure is counting and a frequency so obtained represents the properties of a set by number rather than by the list of elements it contains. Aggregation gives rise to macro theories of micro processes and yields measures and insights not demonstrable by means of the units aggregated thereby. E.g., the statement "the average family has 2.5 children" describes the property of an aggregate, not of a real family. The correlation coefficient is also a measure that aggregates numerous observations neither is capable of demonstrating that relation by itself. Quantum physics, economics and the social sciences are most successful in describing their objects as aggregates. Aggregation is justifiable whenever units are sufficiently independent and similar, e.g., in expressing political opinions through voting or market preferences through individual purchases. Aggregation leads to misleading indicators and theories whenever the whole collection exhibits an organization not expressed in a mere summation (see system, EXTERNALITIES). In econometrics, that difference is represented in so-called interaction effects. (krippendorff ))

Aggregation
A distribution of parasites amongst hosts is said to be aggregated, or overdispersed, if parasites are found to co-occur in particular hosts more often than if the parasites were distributed at random amongst all hosts. A more precise test would be if the distribution differed significantly from a Poisson distribution; a good heuristic is whether the variance to mean ratio is bigger than unity (in appropriate units). Macroparasites are typically aggregated in their host populations, so that the majority of hosts harbor few or no parasites while a few hosts harbor large parasite burdens. Aggregated distributions are often well described empirically by the negative binomial distribution
