Data sources and confidence
The provenance labels used throughout MARA.
Every significant value in MARA carries a source and a status so you can tell data from estimate at a glance.
| Label | Means |
|---|---|
| Verified | From an authoritative source. |
| Imported | Read from the listing page. |
| User-provided | Entered by you. |
| Estimated | Produced by MARA's analysis layer or by a configured cost assumption. |
| Unavailable | Not known. Shown as unknown, never guessed. |
Analyses also carry a data-sources panel listing, for that specific analysis, which values came from the listing, which you supplied, and which MARA estimated.
