Hi met-help,
How do I configure wavelet-stat to run without any thresholding, i.e., apply the wavelet transform on the raw field?
Thanks,
May

Hello May,
It looks like you are unsure about how to set up your wavelet stat
config
file for performing transformations on the raw field. This ticket is
being
assigned to John Halley Gotway.

Minna

Hi May,
The wavelet-stat tool can only be run after applying a threshold. It
is
not designed to be run on a raw, un-thresholded field. It implements
the
method described in Casati, et al (2004) which includes thresholding.
If
you have followup questions about the science or statistics behind it,
I
could refer you Tressa Fowler, a statistician on our team. I just
added
her to this ticket so she'll get a copy of future correspondence.
Thanks,
John

Hi John and Tressa,
Thanks for the quick response. From my understanding of the Casai et
al. 2004 method, their skill score is based on the binary image error.
Does this mean I can only get the wavelet decomposition of a
thresholded binary field using the wavelet-stat tool? Is there a way
to get the scale decomposition of the actual precipitation field
(thresholded or not)?
Thanks again,
May

May,
No, there is no way to get the scale decomposition of the actual
precipitation field using the wavelet-stat tool. That logic is not
currently supported.
