This page includes the information on how to access the [http://socr.ucla.edu/htmls/SOCR_Analyses.html Two Independent Kruskal Wallis Test] library via shell-based command-line interface on local machines. More information about [[SOCR_EduMaterials_AnalysesCommandLine | other SOCR Analyses command-line interfaces is available here]].

== Introduction ==
In addition to the graphical user interfaces, via a web-browser, all [http://socr.ucla.edu/htmls/SOCR_Analyses.html 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, 4 is set defaulted.

==Friedman Test Usage==
* Generic Setting:
<code>
java -cp [SOCRjar_location]/SOCR_core.jar:[SOCRjar_location]/SOCR_plugin.jar edu.ucla.stat.SOCR.analyses.command.TwoIndependentKruskalWallisCSV [data_location]/kw.txt -h [number_of_variables] 4
</code>

* Example: Edit a new file (TwoIndependentKruskalWallisCSV.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.
<code>#!/bin/csh</code>

<code>date</code>

<code>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.TwoIndependentKruskalWallisCSV /cxfs/ccb/CCB_SW_Tools/others/Statist
ics/SOCR_Statistics/SOCR_CSV_test_Scripts_Data/kw.txt -h 4</code>

<code>date</code>

<code>exit</code>

==Example Input data files==
One test datafile is included with the SOCR analyses command-line distribution ('''kw.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.
