The last line should be the series (x(2),x(4),...,x(n)).

The DB2 filters should have + sign before \sqrt 3 in the third number of d_n^L,r_n^H and the second number of d_n^H and r_n^L.

Note: The Pearson Correlation Coefficient only holds if either a) n is large and the sample standard deviation (divided by n-1) is used or b) if the population standard deviation (divided by n) is used.

Last sentence should read: "A normalized Euclidean distance of \sqrt {2n} corresponds to 0 correlation. Also normalized Euclidean distances larger than \sqrt {2n} give negative correlation, with normalized (squared) Euclidean distances of 2\sqrt n corresponding to the perfect anti-correlation -1."
