fastlowess / StreamingSmoothOptions

Interface: StreamingSmoothOptions

Section titled “Interface: StreamingSmoothOptions”

Defined in: index.d.ts:296

Configuration options for streaming LOWESS smoothing.

A subset of [SmoothOptions]: cross-validation, the sorted output, and backend are Batch-only and have no equivalent here, so they aren’t fields on this type.
