A red flag pattern definition.

Fields

name: String

Unique name of the pattern.

description: String

Human-readable description.

category: RedFlagCategory

Category of the flag.

strength: RedFlagStrength

Strength of the flag.

fraud_probability: f64

Base probability that this flag indicates fraud.

inject_with_fraud: f64

Probability of flag appearing when fraud is present: P(flag | fraud).

inject_without_fraud: f64

Probability of flag appearing in legitimate transactions: P(flag | not fraud).

detection_methods: Vec<String>

Detection methods effective for this flag.

related_schemes: Vec<String>

Related fraud schemes.

Implementations

impl RedFlagPattern

pub fn new( name: impl Into<String>, description: impl Into<String>, category: RedFlagCategory, strength: RedFlagStrength, fraud_probability: f64, inject_with_fraud: f64, inject_without_fraud: f64, ) -> Self

Creates a new red flag pattern.

pub fn with_detection_methods(self, methods: Vec<impl Into<String>>) -> Self

Adds detection methods.

pub fn with_related_schemes(self, schemes: Vec<impl Into<String>>) -> Self

Adds related fraud schemes.

pub fn lift(&self) -> f64

Calculates the lift (how much more likely fraud is when flag is present).
