Multi-source lagged-causal correlation
Last updated 2026-06-14
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
- Connect more than one source, such as your ad platform and your payments tool.
- Let Quri look for moves in one metric that track a later move in another over a delay.
- Read the suggested cause it surfaces on Pulse alongside the anomaly it explains.
- Treat the link as a strong lead to confirm, not a proven cause, before you act.
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.
