This page includes the information on how to access the Chi-Square Model-Fit SOCR Analyses 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 -t 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)
  • A sharp/pound (#) symbol at the beginning of a line in the data files indicates a comment and this line is not interpreted as data.

=Chi-Square Goodness of Fit Model Usage

  • Generic Setting:

<virbatim> java -cp [SOCRjar_location]/SOCR_core.jar:[SOCRjar_location]/SOCR_plugin.jar edu.ucla.stat.SOCR.analyses.command.ChiSquareModelFitCSV [data_location]/c1.txt [data_location]/c2.txt -t 1 </virbatim>

  • Example: Edit a new file (ChiSquareModelFitCSV.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.
