NAME

SemanticWeb::Schema::StatisticalPopulation - A StatisticalPopulation is a set of instances of a certain given type that satisfy some set of constraints

VERSION

version v11.0.0

DESCRIPTION

A StatisticalPopulation is a set of instances of a certain given type that satisfy some set of constraints. The property [[populationType]] is used to specify the type. Any property that can be used on instances of that type can appear on the statistical population. For example, a [[StatisticalPopulation]] representing all [[Person]]s with a [[homeLocation]] of East Podunk California, would be described by applying the appropriate [[homeLocation]] and [[populationType]] properties to a [[StatisticalPopulation]] item that stands for that set of people. The properties [[numConstraints]] and [[constrainingProperties]] are used to specify which of the populations properties are used to specify the population. Note that the sense of "population" used here is the general sense of a statistical population, and does not imply that the population consists of people. For example, a [[populationType]] of [[Event]] or [[NewsArticle]] could be used. See also [[Observation]], and the [data and datasets](/docs/data-and-datasets.html) overview for more details.

ATTRIBUTES

constraining_property

constrainingProperty

Indicates a property used as a constraint to define a [[StatisticalPopulation]] with respect to the set of entities corresponding to an indicated type (via [[populationType]]).

A constraining_property should be one of the following types:

InstanceOf['SemanticWeb::Schema::Integer']

_has_constraining_property

A predicate for the "constraining_property" attribute.

num_constraints

numConstraints

Indicates the number of constraints (not counting [[populationType]]) defined for a particular [[StatisticalPopulation]]. This helps applications understand if they have access to a sufficiently complete description of a [[StatisticalPopulation]].

A num_constraints should be one of the following types:

InstanceOf['SemanticWeb::Schema::Integer']

_has_num_constraints

A predicate for the "num_constraints" attribute.

population_type

populationType

Indicates the populationType common to all members of a [[StatisticalPopulation]].

A population_type should be one of the following types:

InstanceOf['SemanticWeb::Schema::Class']

_has_population_type

A predicate for the "population_type" attribute.
