TC-Stat Tool: General

TC-Stat Functionality

The TC-Stat tool reads the .tcst output file(s) of the TC-Pairs tool. This tools provides the ability to further filter the TCST output files as well as summarize the statistical information. The TC-Stat tool reads .tcst files and runs one or more analysis jobs on the data. TC-Stat can be run by specifying a single job on the command line or multiple jobs using a configuration file. The TC-Stat tool is very similar to the Stat-Analysis tool. The two analysis job types are summarized below:

  • The filter job simply filters out lines from one or more TCST files that meet the filtering options specified.
  • The summary job operates on one column of data from TCST file. It produces summary information for that column of data: mean, standard deviation, min, max, and the 10th, 25th, 50th, 75th, and 90th percentiles, independence time, and frequency of superior performance.
  • The rirw job identifies rapid intensification or weakening events in the forecast and analysis tracks and applies categorical verification methods.
  • The probrirw job applies probabilistic verification methods to evaluate probability of rapid inensification forecasts found in edeck's.

TC-Stat Usage

View the usage statement for TC-Stat by simply typing the following:

Usage: tc_stat  
  -lookin path TCST file or top-level directory containing TCST files (where TC-Pairs output resides). It allows the use of wildcards (at least one tcst file is required).
  [-out file] Output path or specific filename to which output should be written rather than the screen (optional).
  [-log file] Outputs log messages to the specified file
  [-v level] Level of logging
  [-config config_file] | [JOB COMMAND LINE(Note: "|" means "or")
  [-config config_file] TCStat config file containing TC-Stat jobs to be run.
  [JOB COMMAND LINE] Arguments necessary to perform a TC-Stat job.

At a minimum, you must specify at least one directory or file in which to find TCST data (using the -lookin path command line option) and either a configuration file (using the -config config_file command line option) or a job command on the command line.
