Struct PoissonResult

    pub deviance: f64,

Result of poisson_fit.

Fields

deviance: f64

Half the Poisson deviance at params.

iterations: usize

Number of steps taken.

converged: bool

Whether the expected-information Newton decrement fell below 1e-6 inside the bounds: within about 0.0014 standard errors of a minimum where the deviance is quadratic there; see poisson_fit.

params: Vec<f64>

Final parameter values (all parameters, including fixed).

covariance: Option<FlatMatrix>

Covariance of the free parameters; the rows and columns of a parameter without an error bar are NaN. None when the fit did not converge or covariance computation is disabled.

uncertainties: Option<Vec<Option<f64>>>

Standard error of each free parameter; None for a parameter on a bound or with a component along a direction the data do not determine, larger than the SVD’s rounding for that parameter. None overall when covariance is.

on_bound: Vec<bool>

Whether each free parameter ended on one of its bounds.
