Struct BreadthView 

pub struct BreadthView {
    pub instruments: Vec<String>,
    pub correlations: Vec<CorrelationRow>,
    pub mean_correlation: Option<f64>,
    pub effective: Option<f64>,
    pub overstatement: Option<f64>,
}

How much of a panel’s apparent breadth is real.

The pooled statistics read as evidence in proportion to the instrument count — three that agree feel like three times the confidence of one. They are not, if the three moved together.

Fields

instruments: Vec<String>

correlations: Vec<CorrelationRow>

Square and symmetric. None where a pair had too little overlap to say — which is different from a correlation of zero.

mean_correlation: Option<f64>

effective: Option<f64>

How many independent instruments the panel behaves like.

overstatement: Option<f64>

How much the pooled average’s certainty is overstated by counting instruments instead of independent ones.

Implementations

impl BreadthView

pub fn mean_correlation(&self) -> f64

Returns the value of mean_correlation, or the default value if mean_correlation is unset.

pub fn effective(&self) -> f64

Returns the value of effective, or the default value if effective is unset.

pub fn overstatement(&self) -> f64

Returns the value of overstatement, or the default value if overstatement is unset.
