Struct AutoETS 

pub struct AutoETS { /* private fields */ }

Automatic ETS model selection.

Implementations

impl AutoETS

pub fn new(season_length: usize, spec: String) -> Result<AutoETS, JsValue>

Create a new AutoETS model search instance.

Errors

If the spec string is invalid, this function returns an error.

pub fn fit(&mut self, y: Float64Array) -> Result<(), JsValue>

Search for the best model, fitting it to the data.

The model will be stored on the inner AutoETS instance, after which forecasts can be produced using its predict method.

Errors

If no model can be found, or if any parameters are invalid, this function returns an error.

pub fn predict( &self, horizon: usize, level: Option<f64>, ) -> Result<JsValue, JsValue>

Predict the next horizon values using the best model, optionally including prediction intervals at the specified level.

level should be a float between 0 and 1 representing the confidence level.

Errors

This function will return an error if no model has been fit yet (using AutoETS::fit).

Trait Implementations

impl Debug for AutoETS

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<AutoETS> for JsValue

fn from(value: AutoETS) -> Self

Converts to this type from the input type.

impl FromWasmAbi for AutoETS

type Abi = u32

The Wasm ABI type that this converts from when coming back out from the ABI boundary.

unsafe fn from_abi(js: u32) -> Self

Recover a Self from Self::Abi.

impl IntoWasmAbi for AutoETS

type Abi = u32

The Wasm ABI type that this converts into when crossing the ABI boundary.

fn into_abi(self) -> u32

Convert self into Self::Abi so that it can be sent across the wasm ABI boundary.

impl LongRefFromWasmAbi for AutoETS

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RcRef<AutoETS>

Same as RefFromWasmAbi::Anchor

unsafe fn long_ref_from_abi(js: Self::Abi) -> Self::Anchor

Same as RefFromWasmAbi::ref_from_abi

impl OptionFromWasmAbi for AutoETS

fn is_none(abi: &Self::Abi) -> bool

Tests whether the argument is a “none” instance. If so it will be deserialized as None, and otherwise it will be passed to FromWasmAbi.

impl OptionIntoWasmAbi for AutoETS

fn none() -> Self::Abi

Returns an ABI instance indicating “none”, which JS will interpret as the None branch of this option.

impl RefFromWasmAbi for AutoETS

type Abi = u32

The Wasm ABI type references to Self are recovered from.

type Anchor = RcRef<AutoETS>

The type that holds the reference to Self for the duration of the invocation of the function that has an &Self parameter. This is required to ensure that the lifetimes don’t persist beyond one function call, and so that they remain anonymous.

unsafe fn ref_from_abi(js: Self::Abi) -> Self::Anchor

Recover a Self::Anchor from Self::Abi.

impl RefMutFromWasmAbi for AutoETS

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RcRefMut<AutoETS>

Same as RefFromWasmAbi::Anchor

unsafe fn ref_mut_from_abi(js: Self::Abi) -> Self::Anchor

Same as RefFromWasmAbi::ref_from_abi

impl TryFromJsValue for AutoETS

type Error = JsValue

The type returned in the event of a conversion error.

fn try_from_js_value(value: JsValue) -> Result<Self, Self::Error>

Performs the conversion.

impl VectorFromWasmAbi for AutoETS

type Abi = <Box<[JsValue]> as FromWasmAbi>::Abi

unsafe fn vector_from_abi(js: Self::Abi) -> Box<[AutoETS]>

impl VectorIntoWasmAbi for AutoETS

type Abi = <Box<[JsValue]> as IntoWasmAbi>::Abi

fn vector_into_abi(vector: Box<[AutoETS]>) -> Self::Abi
