This page will list all known errata for Statistical Methods in Bioinformatics: An Introduction (EDITION 2), by Warren Ewens and Gregory Grant.

**Page 3** line 25: 'observe 26' should be 'observe 11'.
**Page 30** in figure 1.11: The label of the Y-axis should be "f_{X}(x)".
**Page 61** Problem 1.37, line 2: There should not be a minus sign.
**Page 71** 1st paragraph section 2.4.2, line 5: "*m*" should be "*n*".
**Page 73** in equation (2.35): "*m*!" should be "*k*!".
**Page 73** 2nd line from bottom of page. "*X*_{i}=(*x*_{1},..., *x*_{i})" should be "*X*_{i}=(*X*_{1},..., *X*_{}i)"
**Page 75** first line, "*f*_{X}_{1}(*x*)" should be "*f*_{X}_{1}(*x*_{1})"
**Page 115** Note: *S*^{2} is used interchangeably with .
**Page 125** It should be stated that there is an (implicit) change of notation on
page 125. The "t" distribution in eqn (3.29) has n degrees of freedom,
not (as might be expected from the preceding lines) n-1 degrees of freedom.
**Page 160** equation (4.17): *e*^{{λ t}} should be *e*^{{-λ t}}
**Page 160** equation (4.18): (*m*-*j*-1) should be (*m*-*j*+1).
**Page 190** The reference to eqn (1.53) in line 3 of page 190 should be to eqn (5.13).
**Page 193** The upper terminals
in the integration (5.25) on page 193 are incorrect. They should be
replaced (from outermost to innermost) by 1-(g-1)u, v_{2}, v_{3}, ..., v_{g},
where v_{i} = w_{i} - (g-i)u, i = 2, 3, ..., g.
**Page 218** problem 5.13: The reference in the third line should be to equation (5.84), not (5.85).
**Page 223** bottom paragraph states "...[there] are five of these: the subsequences 'a'
in position 3, ..." which should read
"... are six of them: the subsequences 'g' in position 1, 'a' in position 3, ..."
**Page 267** equation (7.38). The first "+" sign should be removed, the second should be changed into a "-".
**Page 267** equation (7.40). Both "+" signs should be changed to "-" signs.
**Page 279** equation (8.6). The capital *X*'s should have subscripts 1, 2, ..., *n*.
**Page 301** problem 8.6 (iii): (16- π^{2}/16 π^{2}) should be (16- π^{2}/16 λ^{2}).
**Page 453** line 7: *V* ' should be *V*^{0}.
**Page 453** line 11: *V*_{0} should be *V*^{0}.
**Page 454** line 6: "variainces" should be "variances".
**Page 458** Formula (13.7) and the formula preceding it: the subscript on *P* should be "(i)" indicating the i-th **ranked** *p*-value.
**Page 458** Formula (13.8): the subscript on *T* should be "(i)" indicating the i-th **ranked** *p*-value.
