How this service works
Sampling observations — Two-measure correlation + Keyed dataset comparison: Two-measure correlation + Keyed dataset comparison for supplied sampling observations records (sample_value, sample_weight). 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 analytical reports: (1) a two-measure correlation report quantifying the statistical relationship between sample_value and sample_weight across the supplied rows, and (2) a keyed dataset comparison report identifying differences between the primary and secondary datasets matched by row_id. All analysis is performed locally on supplied data with no external lookups.
Example use cases
Survey response weight correlation check
“I have 150 survey response records with a sample_value (score) and sample_weight (respondent weight) per row — can you compute the correlation between those two measures and also compare this dataset against last month's baseline dataset matched by row ID?”
A/B test sampling dataset comparison
“I ran two variants of a sampling experiment and have records for each with row IDs, dates, group labels, sample values, and weights. Can you correlate sample_value with sample_weight in the main dataset and then do a keyed comparison between the two variant datasets to see where they differ?”
Quality control for weighted production samples
“We collected 80 production sampling records across two time periods — each row has a date, a group, a measured value, and a weighting factor. Please run the two-measure correlation on the current period data and compare it against the prior period dataset keyed by row ID.”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ib26-analytics-15-183?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need both a correlation between two numeric measures (sample_value and sample_weight) and a row-keyed comparison between two versions of a dataset in a single low-cost call. It is ideal for offline/batch statistical analysis of sampling observation data up to 200 rows where no live data lookup, prediction, or external action is required. It bundles two reports for $0.01 USDC, making it cost-effective compared to calling separate analytical services.
Side effects
- Input array exceeds 200 rows — request will be rejected
- Missing required fields (row_id, dataset_group, date, sample_value, sample_weight) cause validation errors
- Date values not matching YYYY-MM-DD pattern will fail schema validation
- Null values in sample_value or sample_weight may reduce correlation accuracy or cause computation errors
- Mismatched row_ids between primary and secondary datasets may reduce keyed comparison coverage
- Fewer than 2 rows supplied may produce degenerate or undefined correlation results
