Struct ResidualErrorModels 

pub struct ResidualErrorModels { /* private fields */ }

Collection of residual error models for multiple output equations

This mirrors crate::ErrorModels but for parametric algorithms.

Implementations

impl ResidualErrorModels

pub fn new() -> ResidualErrorModels

Create an empty collection

pub fn add(self, outeq: usize, model: ResidualErrorModel) -> ResidualErrorModels

Add an error model for a specific output equation

pub fn get(&self, outeq: usize) -> Option<&ResidualErrorModel>

Get the error model for a specific output equation

pub fn get_mut(&mut self, outeq: usize) -> Option<&mut ResidualErrorModel>

Get a mutable reference to the error model for a specific output equation

pub fn sigma(&self, outeq: usize, prediction: f64) -> Option<f64>

Compute sigma for a specific output equation and prediction

pub fn len(&self) -> usize

Number of error models

pub fn is_empty(&self) -> bool

Check if collection is empty

pub fn iter(&self) -> impl Iterator<Item = (usize, &ResidualErrorModel)>

Iterate over (outeq, model) pairs

pub fn log_likelihood( &self, outeq: usize, observation: f64, prediction: f64, ) -> Option<f64>

Compute log-likelihood for a single observation given its prediction

Arguments

• outeq - Output equation index
• observation - The observed value (y)
• prediction - The model prediction (f)

Returns

The log-likelihood contribution, or None if outeq is invalid.

pub fn total_log_likelihood<I>(&self, obs_pred_pairs: I) -> f64

where I: IntoIterator<Item = (usize, f64, f64)>,

Compute total log-likelihood for multiple observation-prediction pairs

Arguments

• obs_pred_pairs - Iterator of (outeq, observation, prediction) tuples

Returns

The sum of log-likelihood contributions. Returns f64::NEG_INFINITY if any outeq is invalid.

pub fn update_sigma(&mut self, new_sigma: f64)

Update all models with a new sigma estimate
