Expand description

Everything one report site saw for one key.

Fields§

§total: Weight

Weight of the worlds that reached the report.

§yes: Weight

Of the reported facts, the weight where they’re true.

§facts: Weight

Weight of the reported facts.

§values: FxHashMap<Value, Weight>

Weight of every other reported value.

§missing: Weight

Weight of reported distributions’ missing mass.

Implementations§

Source§

impl Acc

Source

pub fn is_event(&self) -> bool

Whether every reported value was a fact (or a distribution of facts).

Source

pub fn chance(&self) -> f64

The probability that the reported fact is true, among the resolved worlds that reached the report.

Source

pub fn chance_bounds(&self, unresolved: Weight) -> (f64, f64)

Bounds on that probability, given unresolved weight elsewhere (docs/semantics.md, section 10).

Source

pub fn distribution(&self) -> Vec<(Value, f64)>

The reported values as a sorted distribution, conditional on being resolved (facts count as true/false when mixed with other values).

Source

pub fn sampled(&self) -> bool

Whether the values come from sampled runs.

Source

pub fn contributing_runs(&self) -> u64

Number of independent runs contributing to this report/key. Multiple visits in one run count once.

Source

pub fn effective(&self) -> f64

When sampling: effective sample size using the report denominator’s per-run contributions, including visit multiplicity.

Source

pub fn chance_se(&self) -> f64

When sampling: the standard error of chance.

Source

pub fn mean_se(&self) -> (f64, f64)

When sampling: the mean of the reported numbers and its standard error.

Source

pub fn value_se(&self, value: &Value, p: f64) -> f64

When sampling: the standard error of a value’s probability p.
