Definitions

In plain terms

Linear interpolation draws a straight-line estimate between two endpoints, but using a future endpoint can make it unsuitable for live causal decisions.

Technical

Interpolation requires an ordered coordinate, endpoint eligibility, method, extrapolation rule, gap limit, grouping, and knowledge-time policy.

Scope

An interpolated market value is an estimate, not an executed or directly quoted price.

Examples

  • A governed dataset records interpolation explicitly and preserves the source context needed to interpret it.

Common misconceptions

  • Interpolation does not have one universal meaning or policy without its declared source, scope, and data contract.
