Configure

Stat-Analysis Tool: Configure

Start by making an output directory for Stat-Analysis and changing directories:

mkdir -p ${METPLUS_TUTORIAL_DIR}/output/met_output/stat_analysis

cd ${METPLUS_TUTORIAL_DIR}/output/met_output/stat_analysis

The behavior of Stat-Analysis is controlled by the contents of the configuration file or the job command passed to it on the command line. The default Stat-Analysis configuration may be found in the data/config/StatAnalysisConfig_default file.

Copy the default configuration file into your working directory and rename it:

cp ${MET_BUILD_BASE}/share/met/config/STATAnalysisConfig_default STATAnalysisConfig_tutorial

Open up the STATAnalysisConfig_tutorial file for editing with your preferred text editor.

vi STATAnalysisConfig_tutorial

You will see that most options are left blank, so the tool will use whatever it finds or whatever is specified in the command or job line. If you go down to the jobs[] section you will see a list of the jobs run for the test scripts.

Remove those existing jobs and add the following 2 analysis jobs:

jobs = [
"-job aggregate -line_type CTC -fcst_thresh >273.0 -vx_mask FULL -interp_mthd NEAREST",
"-job aggregate_stat -line_type CTC -out_line_type CTS -fcst_thresh >273.0 -vx_mask FULL -interp_mthd NEAREST"
];

The first job listed above will select out only the contingency table count lines (CTC) where the threshold applied is >273.0 over the FULL masking region. This should result in 2 lines, one for pressure levels P850-500 and one for pressure P1050-850. So this job will be aggregating contingency table counts across vertical levels.

The second job listed above will perform the same aggregation as the first. However, it'll dump out the corresponding contingency table statistics derived from the aggregated counts.

Close the file and run it on the next page.
