(*) ...and of course, building histograms from characters or samples
also means 'grouping adjacent bits', since a character means "8
adjacent bits", a sample means "

Dear Ethan,
You suggested me to be short and concise.
My kind recommendation to you:
1) Read "A Mathematical Theory of Communication".
2) Try to understand Theorem 2.
3) Try to see, when p_i != 1, then H != 0.
I hope this excercise will help you grasp this to
I tested a simple, first-order histogram-based entropy estimate idea
on various 8-bit signed waveforms (message=sample, no correlations
analyzed). Only trivial (non-bandlimited) waveforms were analyzed.
Method:
1) Signal is trivially turned into a histogram.
2) Probabilities assumed based on histo
A linear predictor[1] tries to "predict" the next sample as the linear
combination of previous samples as
x'[n] = SUM [i=1..k] a_i * x[n-i]
where x'[n] is the predicted sample, and a_1, a_2 ... a_k are the
prediction coefficients (weights). This is often called linear
predictive codin

A "message" can be anything - it can be a sample, a bit, a combination
of samples or bits, a set
