climpred.classes.PerfectModelEnsemble

class climpred.classes.PerfectModelEnsemble(initialized: DataArray | Dataset)

An object for “perfect model” prediction ensembles.

PerfectModelEnsemble is a sub-class of PredictionEnsemble. It tracks the control run used to initialize the ensemble for easy computations, bootstrapping, etc.

This object is built on xarray and thus requires the input object to be an xarray.Dataset or xarray.DataArray.

__init__(initialized: DataArray | Dataset) → None

Create a PerfectModelEnsemble object.

Parameters:

initialized – prediction ensemble output.

control

datasets dictionary item of control simulation associated with the initialized ensemble.

uninitialized

datasets dictionary item of uninitialized forecast.

Methods

__init__(initialized)	Create a PerfectModelEnsemble object.
add_control(control)	Add the control run that initialized the prediction ensemble.
bootstrap(*, metric, comparison[, dim, ...])	Bootstrap with replacement according to Goddard et al. [2013].
equals(other)	Check if PredictionEnsemble is equal to other.
generate_uninitialized()	Generate an uninitialized ensemble by resampling from the control simulation.
get_control()	Return the control as an xarray.Dataset.
get_initialized()	Return the xarray.Dataset for the initialized ensemble.
get_uninitialized()	Return the xarray.Dataset for the uninitialized ensemble.
identical(other)	Check if PredictionEnsemble is identical to other.
plot([variable, ax, show_members, cmap, x])	Plot datasets from PredictionEnsemble.
remove_seasonality([seasonality])	Remove seasonal cycle from PredictionEnsemble.
smooth([smooth_kws, how, drop])	Smooth in space and/or aggregate in time in PredictionEnsemble.
verify(*, metric, comparison[, dim, ...])	Verify initialized predictions against a configuration of its members.
