API Reference

fastlowess-wasm

fastlowess-wasm / OnlineSmoothOptions

Interface: OnlineSmoothOptions

Section titled “Interface: OnlineSmoothOptions”

Defined in: fastlowess_wasm.d.ts:134

Configuration options for online LOWESS smoothing. A subset of SmoothOptions: diagnostics, residuals, parallel execution, cross-validation, and the sorted output have no equivalent here. The se output and intervals require update_mode = "full".

Properties

Boundary handling (“extend”, “reflect”, “zero”, “noboundary”). Default: “extend”.

delta?

Section titled “delta?”

optional delta?: number

Defined in: fastlowess_wasm.d.ts:140

Delta for interpolation speedup. Default: auto. Set to 0 to disable.
