fastlowess / OnlineSmoothOptions

Interface: OnlineSmoothOptions

Section titled “Interface: OnlineSmoothOptions”

Defined in: index.d.ts:179

Configuration options for online LOWESS smoothing.

A subset of [SmoothOptions]: diagnostics, residuals, parallel execution, cross-validation, the sorted output, and backend are all no-ops for online processing (it handles one point at a time), so they aren’t fields on this type. The se output and intervals require update_mode = "full".

Properties

Section titled “Properties”

auto_converge?

Section titled “auto_converge?”

optional auto_converge?: number

Defined in: index.d.ts:200

Auto-convergence tolerance. Default: None.

boundary_policy?

Section titled “boundary_policy?”

Defined in: index.d.ts:196

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

delta?

Section titled “delta?”

optional delta?: number

Defined in: index.d.ts:188

Delta for interpolation speedup. Default: NaN (auto). Set to 0.0 to disable interpolation.

Smoothing fraction (0 < fraction <= 1). Default: 0.67.

intervals?

Section titled “intervals?”

optional intervals?: IntervalsOptions

Defined in: index.d.ts:207

Confidence/prediction levels and per-window residual-bootstrap refits. Requires update_mode = "full".

iterations?

Section titled “iterations?”

optional iterations?: number

Defined in: index.d.ts:183

Number of robustness iterations. Requires update_mode = "full". Default: 0.

missing?

Section titled “missing?”
