Struct KsTest 

Source 
pub struct KsTest<A: Float + Send + Sync> { /* private fields */ }
Expand description

Two-sample Kolmogorov-Smirnov test.

The statistic is D = max_x |F_ref(x) - F_cur(x)| over the merged support of the two samples and the p-value comes from the asymptotic Kolmogorov distribution at sqrt(n_eff) D, n_eff = n_ref n_cur / (n_ref + n_cur). This is a genuine distribution test: it reacts to changes in shape or spread that leave the mean untouched, which none of the mean-shift detectors above can see.

Implementations§

Source§

impl<A: Float + Send + Sync> KsTest<A>

Source

pub fn new(sensitivity: f64, significance_level: f64) -> Result<Self, String>

Creates a KS test whose rejection level is sensitivity (falling back to the configured significance level when that is the tighter of the two).
