This page includes the information on how to access the Friedman Test library via shell-based command-line interface on local machines. More information about other SOCR Analyses command-line interfaces is available here.

Introduction

In addition to the graphical user interfaces, via a web-browser, all SOCR Analyses allow command-line shell execution on local systems.

General Usage

  • Get the latest SOCR JAR files from the SOCR page (http://socr.ucla.edu/htmls/jars/).
  • The command-line interface to SOCR Analyses generally uses EXAMPLE 1 from the list of example data files for the corresponding analysis.
  • All Input files are ASCII (see examples within each of the specific analyses).
  • a -h flag at the end of the command-line indicates that the first row in all ASCII input data files is a HEADER row (so it's not interpreted as data)
  • Number of variables have to be indicated at the end (after -h flag). If no number of variable is included, 5 is set defaulted.

Friedman Test Usage

  • Generic Setting:

java -cp [SOCRjar_location]/SOCR_core.jar:[SOCRjar_location]/SOCR_plugin.jar edu.ucla.stat.SOCR.analyses.command.TwoIndependentFriedmanCSV [data_location]/f.txt -h [number_of_variables] 5

  • Example: Edit a new file (TwoIndependentFriedmanCSV.csh) using any editor and paste this inside (make sure the file has executable permisions). Some operating systems/platforms may require variants of this (C-shell) script.

#!/bin/csh

date

java -cp /cxfs/ccb/CCB_SW_Tools/others/Statistics/SOCR_Statistics/bin/SOCR_core.jar:/ cxfs/ccb/CCB_SW_Tools/others/Statistics/SOCR_Statistics/bin/SOCR_plugin.jar edu.ucla. stat.SOCR.analyses.command.TwoIndependentFriedmanCSV /cxfs/ccb/CCB_SW_Tools/others/Statist ics/SOCR_Statistics/SOCR_CSV_test_Scripts_Data/f.txt -h 5

date

exit

Example Input data files

One test datafile is included with the SOCR analyses command-line distribution (f.txt). The ASCII content of each of these is included below. Note that the first lines in these files are column headers. This requires the "-h" flag at the end of the command line execution so that these first lines are interpreted as column headers.

f.txt
