How this service works
Event attendance - Two-measure correlation: Two-measure correlation for Event attendance. Up to 200 supplied typed records. Local numeric and data-quality processing; no external enrichment or forecasting. One of 25 profiles or calculations across 20 shared operations in this sector. 0.01 USDC includes one bounded two-measure correlation deliverable.
Output
Returns a bounded two-measure correlation deliverable — specifically the computed correlation coefficient between the two numeric measures (registrations and attendees) across the supplied rows, along with any supporting data-quality indicators, computed locally without external enrichment.
Example use cases
Conference registration-to-attendance correlation
“I have registration and actual attendance counts for 50 conference sessions from this year — can you run a two-measure correlation on those numbers to see how well our pre-event registrations predicted real turnout?”
Webinar no-show pattern analysis
“We ran 80 webinars over the past quarter, and I've got the registration count and the actual attendee count for each. Can you correlate those two measures so I can understand if registration volume is a reliable signal of actual attendance?”
Event type comparison for marketing planning
“I have attendance data split across two event types — in-person and virtual — with registration and attendee figures for each date. Please compute the two-measure correlation between registrations and attendees so I can figure out which event format converts sign-ups to real participants more predictably.”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-sector-analytics-event-attendance-correlation?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, local statistical correlation between exactly two numeric event-attendance measures (registrations and attendees) on up to 200 records, without requiring external data enrichment, forecasting, or multi-variable analysis. Prefer it over general analytics APIs when you want a bounded, reproducible, pay-per-call computation at minimal cost ($0.01 USDC).
Side effects
- Fewer than 1 row supplied — returns validation error
- Row missing required fields (row_id, event_type, date, registrations, attendees) — returns schema validation error
- More than 200 rows submitted — rejected due to maxItems constraint
- Numeric values outside allowed range (±1,000,000,000,000) — rejected
- Malformed date string not matching YYYY-MM-DD pattern — rejected
- All values constant (zero variance) — correlation undefined, may return null or error
- Insufficient numeric variance to compute meaningful correlation
