Struct ZscoreSeries 

pub struct ZscoreSeries { /* private fields */ }

Computes the z-score for each series within a group-by family. For each group at each timestamp, the output is (value - mean) / stddev, where mean and stddev are computed across all groups in the family at that timestamp, using the interpolation configuration to align values across groups. When stddev is zero at a timestamp (e.g., all groups have the same value), that data point is excluded from the output. If groupByTags is empty, all groups in the input series will be considered as a single family. This node only produces meaningful results when the input has a group by.

Implementations

impl ZscoreSeries

pub fn builder() -> Builder<InputStage>

Returns a new builder.

impl ZscoreSeries

pub fn new(input: NumericSeries) -> Self

Constructs a new instance of the type.

pub fn input(&self) -> &NumericSeries

pub fn group_by_tags(&self) -> &BTreeSet<StringConstant>

Tags to group by for the normalization. If left empty, all groups in the input will be considered as a single family. Otherwise, inputs will be normalized separately across the groups specified by the tags.

pub fn interpolation_configuration(&self) -> Option<&InterpolationConfiguration>

Configuration for aligning values across groups at each timestamp. Defaults to forward fill interpolation with a 1s interpolation radius.

Trait Implementations

impl Clone for ZscoreSeries

fn clone(&self) -> ZscoreSeries

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ZscoreSeries

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ZscoreSeries

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<ZscoreSeries> for Builder<Complete>

fn from(v: ZscoreSeries) -> Self

Converts to this type from the input type.

impl Hash for ZscoreSeries

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for ZscoreSeries

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for ZscoreSeries

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for ZscoreSeries

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for ZscoreSeries

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
