Module stats 

Pure statistical computation — no plotters dependency.

Everything a chart type needs to know what to draw (quartiles, KDE curves, ROC/PR points, AUC) is computed here and unit-tested against hand-computed reference values, independently of any rendering. The series layer consumes these outputs and turns them into draw calls.

Modules

calibration

Calibration (reliability) binning for probabilistic classifiers.

correlation

Pearson and Spearman correlation, and correlation matrices.

ecdf

Empirical cumulative distribution function (ECDF) and its DKW confidence band.

gain

Cumulative gain and lift curves for ranking/classification evaluation.

histogram

Histogram binning with several standard bin-count rules.

kde

Gaussian kernel density estimation, used to shape violin plots.

normal

Standard-normal inverse CDF (quantile function), for theoretical quantiles on Q–Q plots.

precision_recall

Precision–recall curve: threshold sweep producing (recall, precision) points and average precision (AP).

quartiles

Quartiles, IQR, and Tukey whisker/outlier bounds for box plots.

roc

ROC curve: threshold sweep producing (FPR, TPR) points, and AUC via trapezoidal integration.

Enums

StatsError

Errors returned by the statistics routines for inputs where a metric is undefined, rather than letting NaN propagate silently into a chart.
