Struct BetaConfig 

pub struct BetaConfig {
    pub alpha: f64,
    pub beta: f64,
    pub lower_bound: f64,
    pub upper_bound: f64,
    pub decimal_places: u8,
}

Configuration for Beta distribution.

Fields

alpha: f64

Alpha parameter (shape1) - controls skewness towards 1. Higher alpha = more mass towards 1.

beta: f64

Beta parameter (shape2) - controls skewness towards 0. Higher beta = more mass towards 0.

lower_bound: f64

Lower bound of the output range (default: 0.0).

upper_bound: f64

Upper bound of the output range (default: 1.0).

decimal_places: u8

Number of decimal places for rounding.

Implementations

impl BetaConfig

pub fn new(alpha: f64, beta: f64) -> Self

Create a new Beta configuration.

pub fn percentage(alpha: f64, beta: f64) -> Self

Create a configuration scaled to a percentage range.

pub fn discount_rate() -> Self

Create a configuration for discount percentages (typically 2-15%).

pub fn cash_discount() -> Self

Create a configuration for cash discount rates (1-3%).

pub fn completion_rate() -> Self

Create a configuration for completion rates (biased towards high).

pub fn match_rate() -> Self

Create a configuration for match rates (typically 85-99%).

pub fn quality_score() -> Self

Create a configuration for quality scores (0-100, slightly skewed high).

pub fn uniform() -> Self

Create a uniform distribution on [0, 1].

pub fn validate(&self) -> Result<(), String>

Validate the configuration.

pub fn expected_value(&self) -> f64

Get the expected value (mean) of the distribution.

pub fn mode(&self) -> Option<f64>

pub fn variance(&self) -> f64

Get the variance of the distribution.

impl BetaConfig

pub fn shape(&self) -> BetaShape

Determine the shape of this distribution.
