Struct light_curve_feature::features::LinearFit

pub struct LinearFit {}

Slope, its error and reduced $\chi^2$ of the light curve in the linear fit

Least squares fit of the linear stochastic model with Gaussian noise described by observation errors ${\delta_i}$: $$ m_i = c + \mathrm{slope},t_i + \delta_i \varepsilon_i $$ where $c$ is a constant, ${\varepsilon_i}$ are standard distributed random variables.

Feature values are $\mathrm{slope}$, $\sigma_\mathrm{slope}$ and $\frac{\sum{((m_i - c - \mathrm{slope},t_i) / \delta_i)^2}}{N - 2}$.

• Depends on: time, magnitude, magnitude error
• Minimum number of observations: 3
• Number of features: 3
