p. 8, line -1, “Also, the” Hanging sentence that should be deleted. [James Helmreich, Dec 28, 2017]

p. 135, lines 16-18, The sentence “In this case the coefficient for pulse…status.” should be removed altogether. It is a left-over from the example used in the 1st edition. [James Helmreich, Dec 28, 2017]

p. 164: This page contains some really annoying errors in particular that the odds of the 7 and 10 year olds have been swapped. The text should read

The odds ratio for wheezing for a random child aged 10 relative to a random child aged 7 are \(\exp(-0.3755) = 0.687\). Thus, the odds for wheezing at age 10 are 0.687 times the odds for wheezing at age 7 with a confidence interval that is \(\exp(-0.3755 \pm 1.96\times0.1467) = (0.515, 0.916).\)

Also, the naive standard errors in the last output box shows the eight standard errors from the first model,

`model`

, and not from`model2`

which was referenced in the text just above the box. The output from`model2`

can be seen below`sqrt(diag(model2$geese$vbeta.naiv))`

`## [1] 0.136 0.132 0.134 0.144 0.177`
