# Business Event Participation — Two-Measure Correlation + Secondary-Measure Weighted Mean

> Business Event Participation — Two-Measure Correlation + Secondary-Measure Weighted Mean is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-20).

Computes Pearson correlation between attendee_count and company_count, plus a weighted mean for a secondary measure, across up to 200 business event participation rows.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability business-event-participation-two-measure-correlation-secondary-f343eecd -d '<json body>'
```

Example prompt: Can you run a two-measure correlation and secondary-measure weighted mean on my business event participation data? Here are up to 200 rows with row_id, company_group, date, attendee_count, and company_count — use attendee_count as the primary field.

## When to prefer this

Choose this endpoint when you have business event participation records with attendee and company count columns and need both a correlation coefficient between the two measures and a weighted mean — all in a single paid call covering two analytical reports. Ideal for event analytics pipelines where you want lightweight, local statistical computation without sending data to a full-featured analytics platform.

## Known failure modes

- Fewer than 1 row submitted — validation error
- More than 200 rows submitted — rejected with max-items error
- Missing required fields (row_id, company_group, date, attendee_count, company_count) — schema validation failure
- Invalid date format (not YYYY-MM-DD) — pattern validation error
- Null values in both measures causing undefined correlation — may return NaN or error
- Invalid field enum value — rejected with enum constraint error

## How this service works

Business event participation — Two-measure correlation + Secondary-measure weighted mean: Two-measure correlation + Secondary-measure weighted mean for supplied business event participation records (attendee_count, company_count). Up to 200 rows; 2 independent reports using shared local analytical engines. No live lookup, prediction, professional assessment or external action. 0.01 USDC includes 2 supplied-data reports for up to 200 rows.

## Output

Returns two independent statistical reports: (1) a correlation coefficient measuring the linear relationship between attendee_count and company_count across the supplied rows, and (2) a weighted mean for the secondary measure across those same rows. No external data is fetched; all computation is performed locally on the submitted data.
