Hrm, well, one could drive the proverbial truck through that opening ... Bayesian inference is useful and interesting, yet it doesn't require any mathematical machinery more sophisticated than the integral (and even that in an elementary way). My pet peeve is that the hack job that is the statistical significance test and its associate raft of BS has been foisted on generations of unsuspecting students, who become impervious to a simpler, stronger approach since it would mean dumping all the crap they had to work so hard to assimilate.

See: http://maxima.sourceforge.net/docs/manual/en/maxima.html Questions about tensors and GR should be directed to the mailing list. [email protected] I don't know anything about tensors.
