tools for moderation analysis

there's a couple of small tools we made for support of moderation analysis:

SiSSy creates spss syntax for moderation analysis following aiken & west (1991) (for a continuous or dichotomous moderator).
VYBes lets you create spss code to output a graph of the moderation obtained in SiSSy and VYBes2U generates that graph online as a png-image.

all three may be found at http://stattools.researchx.net


watch out: javascript required. also: unless viewed with firefox, the design may be ugly.
