Errata for Linear Mixed Models: A Practical Guide using Statistical Software (Second Edition) Brady T. West, Kathy Welch, Andrzej Galecki 1. On page 26, in Equation (2.15), there should not be a hat over the V matrix (as this section assumes that V is known). h/t to Mark Mulvey for pointing this out. 2. On page 45, in Table 2.5, there is a missing power of 2 in the formula for the *squared* PRESS residuals. h/t to Abraham Weishaus for catching this! 3. On page 69, in Equation (3.3), the second instance of TREAT1_j in the equation for b_0j should be TREAT2_j. h/t to Elise Radtke for catching this! 4. On page 121, in Equation (3.7), the coefficient of -0.36 should actually be -0.86. h/t to Adam Karnik for catching this! 5. On page 257, in Equation (6.1), the operator before beta_7 should be a +, not an x. h/t to Natasha Paz for spotting this mistake! 6. On page 381, the text refers to a mixture of chi-square distributions with 1 and 2 degrees of freedom; this is a typo, and should refer to 0 and 1 degrees of freedom (consistent with the code and Section 8.5.1). h/t to Yigen Chen for catching this!
