 Here's an SPSS macro for univariate and multivariate tests of skew and kurtosis. (from my 1997 Psychological Methods article).
     Instructions: Save the macro to your hard drive. Open the data you wish to analyze, here's some sample data (Fisher's Iris data).
                                Open a syntax window and enter the commands given in the header of the macro, here's an example of a syntax file.
                          You simply need to edit the INCLUDE statement to give the directory where the macro (normtest.sps) is located and
                          the VARS statement to give the names of the variables in your data file. Have fun analyzing!

 Here's an SPSS macro for Mardia's multivariate skew (more computationally intense).

 Here are LEM and Mplus programs for a mixture signal detection model. (see my 2002 Psychological Review article).

 Here are LEM and Mplus programs for a latent class signal detection model. (see my 2002 Multivariate Behavioral Research article).

 Here's an aML program for a multivariate signal detection model with sample selection. (see my 2003 Journal of Mathematical Psychology article).

 Here's an Mplus program for a multivariate signal detection model. (see my 2003 Journal of Mathematical Psychology article, also see my 2000 EMPG presentation).

 Here are SAS and SPSS programs for signal detection models expressed as generalized linear models. (from my 1998 Psychological Methods article).

Printing Internet Files: To print files downloaded from the Internet, you'll probably need:

ACROBAT

   One type of file has a .pdf extension and requires Adobe Acrobat reader; instructions are given at the website. You'll need this to read and print copies
   of some of the papers given in my publications, presentations, and course syllabi sections.

POSTSCRIPT

   Some people use Postscript files (.ps extension), which can be viewed and printed using Ghostscript and Gsview. Here you can download self-extracting
   files that contain Gsview and Ghostscript for Windows.
