How this service works
Commercial proposal comparisons — Daily sum series + Two-measure correlation: Daily sum series + Two-measure correlation for supplied commercial proposal comparisons records (quoted_amount, delivery_days). 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 analytical reports: (1) a daily sum time series showing aggregated values of the selected measure (quoted_amount or delivery_days) grouped by date, and (2) a two-measure correlation report showing the statistical relationship between quoted_amount and delivery_days across the supplied rows. Both reports are computed locally from the provided data (up to 200 rows) with no external data lookups.
Example use cases
Vendor bid price trend analysis
“I've got 150 proposal records from three competing vendors with dates and quoted amounts — can you compute the daily sum series for quoted_amount and also show me the correlation between quoted amount and delivery days?”
Procurement lead time vs cost correlation
“Here are our RFQ responses from group-a and group-b across the last quarter, each with a quoted price and delivery days. Can you run the daily totals for delivery_days and then check how strongly delivery time correlates with the quoted amount?”
Multi-vendor proposal comparison over time
“I need to compare how quoted amounts from our three supplier groups have trended day by day — please aggregate the daily sums and also calculate the two-measure correlation between quoted_amount and delivery_days for these 80 proposal records.”
