Result of poisson_fit.

Fields

deviance: f64

Half the Poisson deviance of the counts at params, without the priors.

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.

leverage: Option<Vec<f64>>

Each count’s leverage: the diagonal of the hat matrix of the free parameters off their bounds. The leverages sum to the number of directions in those parameters the counts and priors determine, less the share the priors take. None when covariance is None or its decomposition fails.

unbounded: Option<Unbounded>

The free parameters’ Gaussian without their bounds; see Unbounded. None when covariance is, when the decomposition over every free parameter fails, or when a bin predicted zero adds slope to the gradient of a parameter on a bound.
