pint.fitter.WidebandState

class pint.fitter.WidebandState(fitter: Fitter, model: TimingModel, full_cov: bool = False, threshold: float | None = None)[source]

Methods

`predicted_chi2`(step, lambda_)	Predict the chi2 after taking a step based on the linear approximation
`take_step`(step[, lambda_])	Return a new state moved by lambda_*step.
`take_step_model`(step[, lambda_])	Make a new model reflecting the new parameters.
