Configuration for PageHinkley.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

threshold: f64

The detection threshold (λ). When the test statistic exceeds this value, a drift is reported. Must be finite and strictly positive. Larger values reduce false positives but increase detection latency.

warning_threshold: f64

The warning threshold. When the test statistic exceeds this value but not threshold, a warning is reported. Must be in [0, threshold]. Set to 0.0 to disable warnings.

alpha: f64

The forgetting factor (α) applied to the cumulative sum at each step. Must be in (0, 1]. Smaller values make the detector forget old observations faster. 1.0 gives the standard (non-forgetting) Page-Hinkley test.

delta: f64

The allowed drift magnitude (δ). The cumulative sum is penalised by this amount at each step, making the detector less sensitive to small fluctuations. Must be finite and non-negative.

min_samples: u64

Minimum number of samples before any detection is reported. Must be greater than zero.
