# Metrics

Metrics do not modify the object.
Most return a tidy frame with `metric`, `representation`, `key` and `value`, so results from several calls stack; `evaluate_integration` instead draws the scib-metrics integration panel as a heatmap and returns its numeric results frame, one row per representation.

```{eval-rst}

    metrics.evaluate_integration
    metrics.diagnose_testing
    metrics.pc_regression
    metrics.batch_variance_explained
    metrics.variance_carried
