Statistical Procedures

I have created a series of "Custom Dialogues" for installation into SPSS. Many of these procedures are available elsewhere, but psychologists are often slow to adapt to procedures not available in SPSS.  I have found these particular procedures useful and SPSS lacking, so I built these packages.  The procedures are:
  • Attenuated Regression
    • File
    • Web Page
  • Determining the number of factors in SPSS
    • File
    • Web Page
  • Cronbach's alpha confidence intervals
    • File
    • Web Page
  • Omega
  • Unbiased ANCOVA
    • File
    • Web Page
Additionally, if you would rather install the entire suite of programs here, you can do so with this file (I often do this when I update versions of SPSS).

If you are unfamiliar with custom dialogues, I refer you to Andrew Hayes's web link here.
