How this service works
Survey response weights — Adjacent row changes + Equal-width histogram: Adjacent row changes + Equal-width histogram for supplied survey response weights records (response_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
Two analytical reports: (1) an adjacent row changes report showing value deltas between consecutive rows for the selected field, and (2) an equal-width histogram report showing bin boundaries and frequency counts for the chosen field across up to 200 survey records.
Example use cases
Survey panel weight distribution analysis
“I've got 150 survey rows with response values and sample weights by region and date. Can you run an adjacent row change analysis plus a 10-bin equal-width histogram on the response_value field so I can see how responses are distributed and how they shift row by row?”
Weighted response drift monitoring
“I need to check if sample weights in my survey dataset are drifting row by row — can you run the adjacent row changes report plus a histogram with 8 bins on the sample_weight field for my 80 survey records?”
Economics survey summary for regional groups
“Here are 200 survey responses from two regional groups with dates and sample weights from our economics study — please give me an adjacent change report and a 5-bin equal-width histogram on response_value so I can spot any outliers and see the overall distribution.”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ib26-economics-24-156?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need both sequential row-change analysis and histogram binning on survey response or sample weight data in a single call, without needing external data lookups or live prediction — ideal for offline survey dataset QA, economics research summarization, or data pipeline validation steps.
Side effects
- Exceeding 200 rows returns a validation error
- Invalid date format (non YYYY-MM-DD) causes rejection
- Missing required fields (row_id, response_value, sample_weight) causes schema validation failure
- Bin count outside 1–30 range returns an error
- Null values in selected field may affect computation accuracy
