class stormvogel.model.distribution.Distribution[ValueType: stormvogel.model.value.Value, SupportType](distribution: dict[SupportType, ValueType] | list[tuple[ValueType, SupportType]] | Distribution[ValueType, SupportType] | None = None)¶

A sparse distribution mapping support elements to probability values.

_distribution: dict[SupportType, ValueType]¶

property support: set[SupportType]¶: Returns the support of this distribution (elements with non-zero probability).

property probabilities: list[ValueType]¶: Returns the probability values of this distribution.

is_stochastic(epsilon: float = 1e-06) → bool¶

Returns whether this distribution sums to 1.

For interval and parametric distributions we always return True.

__eq__(other: object) → bool¶

__repr__() → str¶

__str__¶

__add__(other: Distribution[ValueType, SupportType]) → Distribution[ValueType, SupportType]¶

__iter__()¶

__len__() → int¶

__getitem__(key: SupportType) → ValueType¶

__setitem__(key: SupportType, value: ValueType)¶

__contains__(key: SupportType) → bool¶
