[Met_help] [rt.rap.ucar.edu #80672] History for question on stats for multiple thresholds

Thu Jun 1 13:38:40 MDT 2017

----------------------------------------------------------------
  Initial Request
----------------------------------------------------------------

Hi,

I would like to display some statistics for 7 thresholds.  First, is there
a limit on the number of thresholds that I can use?

Can I use either my config file, or the command line?

What do I use for the "-job " command?  I can't seem to make any stats for
each of the thresholds.  Can I make RMSE stats, or just what is listed in
the MCTC file?

thanks in advance!

Roz

Hi Roz.  My name is Julie, and I am part of the MET development team.
Unfortunately, John is likely the best person to answer your
questions, but
he is out of the office until next week.  I will do the best I can to
answer your questions for now.

I do not believe there is a limit on the number of thresholds that you
can
use.

I believe that you can use either your config file or the command
line.

Regarding the "-job" command for stat_analysis, it is described in the
MET
User's Guide:
http://www.dtcenter.org/met/users/docs/users_guide/MET_Users_Guide_v6.0.pdf

in section 12.3.2 (starting on pg. 188) and an example is given on pg.
192,
where it also shows the format for an analysis job:

-job job_name REQUIRED and OPTIONAL ARGUMENTS

All possible tasks for "job_name" are listed in Table 12.2 on pg. 193.
Furthermore, I'll give a brief overview of three of the jobs:

1) summary: A summary job selects out a single column of data from one
line
type of your MET output and then gives you summary information about
the
numbers it found in that column of data.

2) aggregate: The aggregate job selects out all the liens of the type
you
requested and then aggregates their contents together into a single
line.
The output line type of the aggregate job is always the same as the
input
line type, but only certain line types can actually be aggregated -
for
example contingency table counts (CTC), partial sums (SL1L2), and so
on.

3) aggregate_stat: The aggregate_stat job does the same things as the
aggregate job described above, but rather than writing out the same
line
type as the input one, it writes out a different one.  This
functionality
only works for certain combinations of line types.  For example, CTC
lines
can be aggregated together and from them we can derive contingency
table
statistics (CTS).  Likewise, we can use SL1L2 lines to derive
continuous
statistics (CNT).

I hope this helps to better answer your questions.  Please let us know
what
other questions you have an I'll do my best to help.

I have seen that you have submitted another met_help ticket.  I will
work
on it and follow up as soon as I can.

Thanks,
Julie

Hi Julie,

Well, that sort of answers my question.  I was able to add in multiple
thresholds, but, as for the exact wording for the "job" might have to
be
answered by John. Also, I have another help ticket in for an error
statement that I was using for ranges in my threshold library.  So,
getting
an answer for that might help with this ticket.
