Expand description
Cusum — a range of cumulative sums
$$ \mathrm{cusum} \equiv \max(S) - \min(S), $$ where $$ S_j \equiv \frac1{N\sigma_m} \sum_{i=0}^j{\left(m_i - \langle m \rangle\right)}, $$ $N$ is the number of observations, $\langle m \rangle$ is the mean magnitude and $\sigma_m = \sqrt{\sum_i (m_i - \langle m \rangle)^2 / (N-1)}$ is the magnitude standard deviation.
- Depends on: magnitude
- Minimum number of observations: 2
- Number of features: 1
