An observed datum used to update a prior.

Variants

Bernoulli

Outcome of a series of Bernoulli trials.

Fields

successes: u64

Number of successes observed.

trials: u64

Total number of trials.

Gaussian

Sufficient statistics from a Gaussian-distributed sample.

Fields

sample_mean: f64

Sample mean.

sample_variance: f64

Sample variance (must be > 0).

n: u64

Sample size.

Categorical

Category counts from a Categorical/Multinomial sample.

Fields

counts: Vec<u64>

Observed count for each category (length must equal Dirichlet dim).

Poisson

Sufficient statistics from a Poisson process.

Fields

total_events: u64

Total events observed.

total_time: f64

Total elapsed time (must be > 0).

Trait Implementations

impl Clone for Observation

fn clone(&self) -> Observation

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Observation

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Observation

fn eq(&self, other: &Observation) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
