Struct RegressionDetector 

Source 
pub struct RegressionDetector {
    pub min_samples: usize,
    pub confidence: f64,
    pub threshold: f64,
    pub require_large_effect: bool,
    pub bootstrap_iterations: usize,
}
Expand description

Performance regression detector. Uses bootstrap confidence intervals per Hoefler & Belli [8].

Fields§

§min_samples: usize

Minimum number of samples for statistical significance.

§confidence: f64

Confidence level for bootstrap CI.

§threshold: f64

Regression threshold (fraction, e.g., 0.05 = 5%).

§require_large_effect: bool

Require large effect size (Cohen’s d >= 0.8) in addition to CI.

§bootstrap_iterations: usize

Number of bootstrap resamples.

Implementations§

Source§

impl RegressionDetector

Source

pub fn new() -> Self

Source

pub fn compare(&self, baseline: &[f64], current: &[f64]) -> RegressionResult
