Struct light_curve_feature::features::StandardDeviation

pub struct StandardDeviation {}

Standard deviation of magnitude $\sigma_m$

$$ \sigma_m \equiv \sqrt{\sum_i (m_i - \langle m \rangle)^2 / (N-1)}, $$

$N$ is the number of observations and $\langle m \rangle$ is the mean magnitude.

• Depends on: magnitude
• Minimum number of observations: 2
• Number of features: 1

Performs copy-assignment from source.

impl Debug for StandardDeviation

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

Formats the value using the given formatter.

impl Default for StandardDeviation

fn default() -> StandardDeviation

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for StandardDeviation

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where
    __D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.

impl<T> FeatureEvaluator<T> for StandardDeviation where
    T: Float, 

fn eval(&self, ts: &mut TimeSeries<'_, T>) -> Result<Vec<T>, EvaluatorError>
