Struct light_curve_feature::features::Kurtosis
source · pub struct Kurtosis {}
Expand description
Excess kurtosis of magnitude
$$ G_2 \equiv \frac{N,(N + 1)}{(N - 1)(N - 2)(N - 3)} \frac{\sum_i(m_i - \langle m \rangle)^4}{\sigma_m^4} - 3\frac{(N - 1)^2}{(N - 2)(N - 3)}, $$ where $N$ is the number of observations, $\langle m \rangle$ is the mean magnitude, $\sigma_m = \sqrt{\sum_i (m_i - \langle m \rangle)^2 / (N-1)}$ is the magnitude standard deviation.
- Depends on: magnitude
- Minimum number of observations: 4
- Number of features: 1
