Page 752 In (2.67), integral should be over R.
Page 991 four lines below equation (2.158), "X1, X2,...,Xn" should be "X(1), X(2), ..., X(n)."

Page 1534 unnumbered equation after (5.4). "(2z-a)" should be "(2L-z)".
Page 1732 Third line of text from the bottom in "that it arises at site n-1 as one of the recurrences" n-1 should be n-2
Page 1742 line 8 of the paragraph below (5.46) "counted occurrences" should be "recurrences".
Page 1794 problem 5.7. Replace "N=5, N=6" by "N=4, N=5".

Page 2072 Figure 6.3, trees are labeled as shown here.

Page 3302 Last paragraph. It should be pointed out that the Beta's are not supposed to be used to solve (11.3). They will be needed in (11.16) and that is why they are solved for here. No relation to (11.3) should be made.
Page 3312 Equation (11.8). The "T" should be a "t".
Page 3382 line 5, d4 should be d5.
Page 3511 three lines above equation (12.3), delete "of".
Page 3522 line 14, add "to" after "wishes".
Page 3521 line 14, change "interval for theta" to "interval for some parameter theta".
Page 3532 line 3 below equation (12.6), change "the data come from" to "theta-cap has".
Page 3552 line 4, change "show" to "claim".
Page 3602 line 10, change "8 choose 4" to "16 choose 8".
Page 3602 lines 29 and 30, replace "If significance ... and so on" by "The method for testing further genes is described by Dudoit et al. (2000)".
Page 3712 3rd line from the bottom, the last two components of l2 should have minus signs.
Page 3912 line 3 from the bottom, remove "not" after "cannot".

Page 4241 second line from the bottom, change "43" to "43".
Page 4292 in first displayed equation, the numerator on the right should be r(r-1)(r-2)...(r-k+1). I.e. there is a missing ellipsis.

Page 4542 In Jukes/Cantor reference, deleted comma after "Cantor".
Page 4562 In Krogh et al., K. Hausler should be D. Haussler
