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
