Subject: Formalized Music page 86

Sorry for diverging, but near the bottom of page 86 of the Pendragon
revised edition of Xenakis' book, we have:
the probability of X (a) remaining X  is .85, (b) changing to Y, is .15
the probability of Y (a) changing to X is .4, (b) remaining Y, is .6

"The entropy of the states of X will be -0.85 log 0.85 - 0.15 log 0.15 =
0.611 bits..."

I've gone over this many times, but no matter what I do, I don't get
anything like .611.  If anyone could shed any light on this, I'd be
grateful.  Apologies for being way off, but I don't know where else to ask.
Cheers
Arne

Hi,

After a touch of digging around through some information theory notes (plus
a nostalgic look through _The Mathematical Theory of Communication_  by
Shannon and Weaver), I found that you need to take those logs base 2. Or,
just take the base 10 figure you got and divide by log(2)=.301

 (-.85 log (.85) - .15 log (.15))/.301 = (.060 + .124)/ .301 = .611 bits


Happy entropy!
