- Distribution-Free Options — Mann-Whitney, Kruskal-Wallis, and permutation overlays.
- Power Overlays — Display achieved power, detectable effect, and sample planning hints.
- Story-Ready Charts — Gradient violins, beeswarm overlays, and confidence brackets.
Dependent Comparisons
Within-subjects workflows that emphasize change profiles:
- Paired t & Wilcoxon — Difference distributions, Bland-Altman plots, and agreement stats.
- Repeated-Measures ANOVA — Sphericity checks, Greenhouse-Geisser corrections, and profile plots.
- Multivariate Repeated Measures — MANOVA-style contrasts for multichannel outcomes.
- Timepoint Storyboards — Align trends, annotate interventions, and export movie loops.
- Sync to VB6 — notifyColumnChanged wires ensure dashboards refresh as soon as data updates.
