Change Point Detection (example data).
Run analysis

The series is smoothed, then a sliding window compares the average before and after each day, flagging a change point when the standardised difference exceeds your sensitivity. Needs at least 14 days.

What you get

  • A sensitivity slider (0.5–3, default 1.5; lower is more sensitive).
  • A line chart with dashed reference lines and the % change at each change point.
  • A table of before/after averages, direction, and change %, plus export.
