  1. Design, measurement, analysis and visualization in SyStat Chong Ho Yu, Ph.D. Instruction, Research and Infrastructure Support Arizona State University March 28, 2000

  2. What is the position of SyStat? • SPSS has specific modules for different functions and purposes. • SyStat packs virtually everything into one package. • Examples…

  3. Design of experiment • SPSS’s Trial Run is made for DOE only. • Include Response Surface Design

  4. Design of Experiment • SyStat has a built-in DOE module but is less powerful. • For more info: http://seamonkey.ed.asu.edu/~alex/teaching/WBI/tr.html

  5. Missing Data Analysis • There is a plug-in for MDA running within SPSS. The method is Expectation Maximization (EM). • SyStat has a built-in MDA but is less powerful. • More info: http://www.utexas.edu/cc/faqs/stat/general/gen25.html

  6. Other built-in features • Resampling Stat is specific for resampling while SyStat has a built-in bootstrap function. • For more info: http://seamonkey.ed.asu.edu/~alex/teaching/WBI/resampling.html • Biolog is for analysis of Item Response Theory while SyStat has a built-in tool for that. • For more info: http://seamonkey.ed.asu.edu/~alex/teaching/WBI/measurement.html

  7. Other built-in features • SAS/Insight, JMP, and DataDesk are for data visualization while multivariate visualization is embedded in SyStat.

  8. Function plot • A regression model is essentially a function. • Visualize multivariate relationships. • Can also be done in Mathematica and Maple, but SyStat is easier. • Regression mesh surface (Dynamic explorer) • Contour • Moasic

  9. Function plot

  10. Parallel Coordinate Display • Examine response pattern across variables • Used to be conducted in BMDP Diamond, but SyStat has this feature • Unstandardized PCD may not be useful when the scales vary.

  11. Parallel Coordinate Display

  12. New feature • Express Graph • Work with SAS 6.12 • Use SAS statistical procedures but SyStat graphics

  13. Conclusion • One package for everything? • Good enough for students but researchers still need specific tools for different jobs.
