Analytica is an automatic theorem prover written in Mathematica 1.1, developed 
by Edmund Clarke and others at Carnegie Mellon University. In March of this 
year it was available via anonymous ftp from "gs204.sp.cs.cmu.edu" in directory
/pub/analytica. 

Andrej_Bauer at PARALLEL.SCANDAL.CS.CMU.EDU was very helpful to me
in getting started with it. 

The ftp available version runs under UNIX. With minor alterations (filename 
changes).  I got Analytica to run under Windows 3.1 and Mathematica 2.0.

My interest is in proving conjectures in Mathematical Statistics. Analytica 
looks like a good starting point, though it will need to be taught a lot of
additional rules.

Good Luck. I'd be interested in hearing about your work (by email).
