Core functions

dfa(values: &[f64]) -> DfaResult

Compute the DFA scaling exponent. Returns alpha and R-squared.

acr(values: &[f64]) -> DfaResult

Compute autocorrelation decay exponent.

analyze(values: &[f64]) -> StructuralLaw

Full structural analysis: DFA + ACR + statistics.

health_check(law: &StructuralLaw, baseline: f64) -> HealthVerdict

Compare current DFA alpha against a baseline.

Types
