pysteps.verification.spatialscores.intensity_scale_init

pysteps.verification.spatialscores.intensity_scale_init(name, thrs, scales=None, wavelet='Haar')

Initialize an intensity-scale verification object.

Parameters:
name : string

A string indicating the name of the spatial verification score to be used:

Name Description
FSS Fractions skill score
BMSE Binary mean squared error
thrs : float or array_like

Scalar or 1-D array of intensity thresholds for which to compute the verification.

scales : float or array_like, optional

Scalar or 1-D array of spatial scales in pixels, required if *name*=”FSS”.

wavelet : str, optional

The name of the wavelet function, required if *name*=”BMSE”. Defaults to the Haar wavelet, as described in Casati et al. 2004. See the documentation of PyWavelets for a list of available options.

Returns:
out : dict

The intensity-scale object.
