Multi-source lagged-causal correlation
Last updated 2026-06-21
Definition
Lagged-causal correlation lines up a move in one source with a delayed move in another to suggest a likely cause. Ad spend today rarely shows up as revenue today; it lands a few days later. Quri checks for moves that track each other across that delay, so you get a plausible reason rather than a coincidence.
How to do this in Quri
- Let detection flag an anomaly — a metric that dropped or spiked beyond its baseline.
- Open it on Pulse or in Analytics, then click "Likely causes" to see what moved first.
- Read the ranked leads: each cross-source signal with its lead time, strength and direction.
- Confirm with the lead-lag overlay — treat the link as a strong lead, not a proven cause.
Frequently asked
- Why the lag instead of same-day matching?
- Effects take time. Spend today turns into revenue over the following days, so Quri compares a move now against a delayed move later, which fits how these metrics actually relate.
- Does a correlation mean one thing caused the other?
- Not on its own. Quri surfaces the most plausible link to save you the hunt, but it points you at a lead to verify rather than asserting a proven cause.
