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 -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 model parameters can be indicated at the end (after -h flag). If no number of model parameter is included, 0 is set defaulted.
Chi-Square Goodness of Fit Model Usage
- Generic Setting:
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 -h [number_of_model_parameters;default_is_0] 1
- Example: Edit a new file (ChiSquareModelFitCSV.csh) using any editor and paste this inside (make sure the file has executable permissions). Some operating systems/platforms may require variants of this (C-shell) script.
#!/bin/csh

Example Input data files
Two test datafiles are included with the SOCR analyses command-line distribution (c1.txt and c2.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.
