Struct StatisticalMetrics 

pub struct StatisticalMetrics {
    pub mean: Duration,
    pub std_dev: Duration,
    pub confidence_interval_lower: Duration,
    pub confidence_interval_upper: Duration,
    pub p_value: Option<f64>,
}

Fields

mean: Duration

std_dev: Duration

confidence_interval_lower: Duration

confidence_interval_upper: Duration

p_value: Option<f64>

Two-sided p-value of a one-sample Student-t test of step_times against a null hypothesis mean, computed by StatisticalAnalyzer::analyze.

A p-value needs a null hypothesis to test against. benchmark_optimizer passes the matching optimizer’s BenchmarkResult::avg_step_time from PerformanceValidator::baseline_results as that hypothesis when one has been set via PerformanceValidator::set_baseline; a low p-value then means this run’s step times are statistically distinguishable from the baseline’s average, in either direction. None when no baseline is set for the optimizer being benchmarked (nothing to test against) – left absent rather than fabricated as a constant.
