Shape-Preserving Bivariate Interpolation
15/15 checkable references clean · checked 2026-10-06
Every reference with a DOI in the deposited reference list resolved to a known work in Crossref or DataCite at the dated check, and none carried a retraction, withdrawal, or removal notice.
6 without a DOI — not checked. A reference deposited without a DOI is never matched by title or guessed at; it stays outside the checked set, and this line discloses that.

What this badge says. CiteStamped means the CHECKABLE references of this
work were clean at the dated check: each resolved to a known work in a public registry, and none
carried a retraction notice at that time. If Crossref’s record marks the work itself
retracted, withdrawn, or removed, the badge says so instead of showing clean. It says nothing
about the quality, findings, or importance of the work itself, and nothing about references
deposited without a DOI.

Embed this badge
Both snippets point at the live badge image and link back to this page. The badge re-renders from the daily check, so an embed never goes stale by more than a day of visits.
