Re: Order being created from disorder?



Earlier today Ludwik asked:

Would the "non-acceptable" conclusion drawn by Brian Whatcott change if
all frequencies were multiplied by a large factor, such as 10000, to
"improve statistical significance"?

That was a silly question; the probabilities f_r/sum(f_r) do not change
when all frequencies are multiplied. The question should have been asked
differently. Can the discrepancies (between the values of D1 and D2, as
calculated by Brian, and our knowledge of the probability distribution)
be due to statistical fluctuations in frequencies invented to represent
real data. Here the value of the "large factor" does become important.
A frequency of 4 (out of 10 throws) can be purely accidental but the
frequency of 40000 (out of 100000 throws) can not fluctuate by more than
about 1%. (To be pedantically correct the low level of fluctuations
should have been matched by the number of digits in table 1, for example,
probability=0.400 instead of 0.4, etc.)

Thus the Brian's question remains valid; we must assume that each
realization involved a vary large number of throws. THE DIFFERENCE
BETWEEN D1 AND D2 DOES NOT REFLECT THE OBVIOUS FACT THAT THE SECOND
DISTRIBUTION OF OUTCOMES WAS VERY COMMON WHILE THE FIRST ONE WAS HIGHLY
UNLIKELY. WHY IS THIS NOT REFLECTED IN SHANON'S ENTROPIES?
