SOCR EduMaterials AnalysesCommandLineSimpleRegression
This page includes the information on how to access the Simple Regression 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)
Simple Regression Usage
- Generic Setting:
java -cp [SOCRjar_location]/SOCR_core.jar:[SOCRjar_location]/SOCR_plugin.jar edu.ucla.stat.SOCR.analyses.command.SimpleRegressionCSV [data_location]/reg.txt -h
- Example: Edit a new file (SimpleRegressionCSV.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
date
java -cp /ifs/ccb/CCB_SW_Tools/others/Statistics/SOCR_Statistics/bin/SOCR_core.jar:/ifs/ccb/CCB_SW_Tools/others/Statistics/SOCR_Statistics/bin/SOCR_plugin.jar edu.ucla.stat.SOCR.analyses.command.SimpleRegressionCSV /ifs/ccb/CCB_SW_Tools/others/Statistics/SOCR_Statistics/SOCR_CSV_test_Scripts_Data/reg.txt -h
date
exit
Example Input data files
One test datafile is included with the SOCR analyses command-line distribution (reg.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.
| reg.txt | |
|---|---|
| x | y |
| 82.0 | 85.0 |
| 97.0 | 98.0 |
| 93.0 | 102.0 |
| 75.0 | 80.0 |
| 87.0 | 90.0 |
| 130.0 | 135.0 |
| 125.0 | 135.0 |
| 126.0 | 131.0 |
| 104.0 | 110.0 |
