x |
a list of equally sized matrices, the first element is assumed to be the observation |
dec |
logical, do you want to use the decimated transform |
xmin |
values smaller than |
log |
logical, do you want to log-transfrom the data? (recommended for precipitation) |
a |
relative weight of directional errors compared to scale errors in |
nbr |
number of breaks for the scale histograms, has no effect if |
rsm |
number of pixels which are linearly smoothed at the edge |
Nx |
size to which the data is extended in x-direction |
Ny |
size to which the data is extended in y-direction |
J |
largest scale considered |
boundaries |
how to handle the boundary conditions, either "pad", "mirror" or "periodic" |
return_specs |
if |
... |
further arguments, currently ignored. |
object |
object of class sadverif |
each element of x is transformed via dtcwt
from the 'dualtrees' package. Scores and centres based on the mean spectra are calculated. If dec=FALSE
, scale histograms and the corresponding score hemd
are calcualted as well.
an object of class sadverif
, containing the following elements
a dataframe containing the parameters that were originally passed to dtverif
a matrix cotaining the anisotropy rho
, angle phi
and central scale z
derived from the mean spectra. Rain area and sum are included as well.
a matrix containing the differences in centre components, the direction/anisotropy score dxy
, the emd between direction-averaged spectra (semd
) and the emd between the directional spectra (semdd
). If dec=FALSE
, the emd between the scale histograms, hemd, is included as well.
the time the calculation took in seconds
if there is more than one forecast, the ensemble scores SpEn and (if available), hemd are computed as well, treating all forecasts as members of the ensemble to be verified.
