Struct light_curve_feature::features::ExcessVariance [−][src]
pub struct ExcessVariance {}
Expand description
Measure of the variability amplitude
$$ \frac{\sigma_m^2 - \langle \delta^2 \rangle}{\langle m \rangle^2}, $$ where $\langle \delta^2 \rangle$ is the mean of squared error, $\sigma_m$ is the magnitude standard deviation. Note that this definition differs from Sánchez et al. 2017
- Depends on: magnitude, error
- Minimum number of observations: 2
- Number of features: 1
