Struct ParetoConfig 

pub struct ParetoConfig {
    pub alpha: f64,
    pub x_min: f64,
    pub max_value: Option<f64>,
    pub decimal_places: u8,
}

Configuration for Pareto distribution.

Fields

alpha: f64

Shape parameter (alpha) - controls tail heaviness. Lower values = heavier tail (more extreme values). Typical values: 1.5-3.0 for financial data.

x_min: f64

Scale parameter (x_min) - minimum value. All samples will be >= x_min.

max_value: Option<f64>

Maximum value (clamps output).

decimal_places: u8

Number of decimal places for rounding.

Implementations

impl ParetoConfig

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

Create a new Pareto configuration.

pub fn capital_expenditure() -> Self

Create a configuration for capital expenditures (heavy tail).

pub fn maintenance_costs() -> Self

Create a configuration for maintenance costs.

pub fn vendor_spend() -> Self

Create a configuration for vendor spend distribution.

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

Validate the configuration.

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

Get the expected value (mean) of the distribution. Only defined for alpha > 1.

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

Get the variance of the distribution. Only defined for alpha > 2.
