# Thesis Milestones Two-Measure Correlation and Missing-Value Fill

> Thesis Milestones Two-Measure Correlation and Missing-Value Fill is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-25).

Computes correlation between completed and planned thesis milestones and fills missing values using a chosen method, across up to 200 submitted 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 thesis-milestones-two-measure-correlation-and-missing-value-fill-c2d0a427 -d '<json body>'
```

Example prompt: I have thesis milestone records for two course groups over the past week — some completed_milestones values are missing. Can you fill those nulls using the median and also run a correlation between completed_milestones and planned_milestones across all 200 rows?

## When to prefer this

Choose this endpoint when you have tabular thesis milestone data (completed vs. planned) with up to 200 rows and need both a correlation analysis and a missing-value imputation in a single $0.01 call. It is purpose-built for education/academic-tracking datasets with the specific completed_milestones and planned_milestones schema. Prefer it over generic stats APIs when you want bundled reports with no external data dependencies and a fixed low cost per batch.

## Known failure modes

- Fewer than 1 row submitted — request rejected
- More than 200 rows submitted — exceeds row limit
- Invalid date format (not YYYY-MM-DD) — validation error
- Missing required fields (row_id, course_group, date) — schema validation failure
- Insufficient non-null values to compute correlation — may return null or NaN correlation
- Invalid fill method value outside enum (zero/mean/median) — error response
- Payment not received or insufficient USDC — 402 Payment Required

## How this service works

Thesis milestones — Two-measure correlation + Explicit missing-value fill: Two-measure correlation + Explicit missing-value fill for supplied thesis milestones records (completed_milestones, planned_milestones). 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 completed_milestones and planned_milestones, and (2) a missing-value fill report where nulls in the chosen field are replaced using the selected method (zero, mean, or median). Both reports are computed locally from the supplied rows without any external data lookup.
