Struct ChainTracker 

pub struct ChainTracker { /* private fields */ }

Tracks statistics for a single MCMC chain.

Fields

• n_params: Number of parameters in the chain.
• n: Number of steps taken.
• p_accept: Acceptance probability.
• mean: Mean of the parameters.
• mean_sq: Mean of the squared parameters.
• last_state: Last state of the chain.
• accept_queue: Queue tracking acceptance history.

Implementations

impl ChainTracker

pub fn new<T>(n_params: usize, initial_state: &[T]) -> Self

where T: ToPrimitive + Clone,

Creates a new ChainTracker with the given number of parameters and initial state.

Arguments

• n_params: Number of parameters in the chain.
• initial_state: Initial state of the chain.

Returns

A new ChainTracker instance.

pub fn step<T>(&mut self, x: &[T]) -> Result<(), Box<dyn Error>>

where T: ToPrimitive + Clone,

Updates the tracker with a new state.

Arguments

• x: New state of the chain.

Returns

Ok(()) if successful; an error otherwise.

pub fn stats(&self) -> ChainStats

Retrieves the current statistics of the chain.

Returns

A ChainStats struct containing the current statistics.

Trait Implementations

impl Clone for ChainTracker

fn clone(&self) -> ChainTracker

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChainTracker

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

Formats the value using the given formatter.

impl PartialEq for ChainTracker

fn eq(&self, other: &ChainTracker) -> 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.
