The second edition is much like the first and is at least a year behind the original schedule. See my review of the first edition to understand why this is a classical. The promised advances in missing data are included and a new author Haegerty has been added. The missing data chapter is three times longer than in the first edition. They cover what they promised. They also mention some of the econometrics literature including the work of Nobel Laureate James Heckman but admit in the preface that they do not know that literature very well and hence do not cover it in depth.
In the past two years Verbeke and Molenberghs have produced a highly competitive book that deals in detail with pattern mixture models and other missing data methodology but curiously Diggle et al. do not reference it even though they do cite some of Molenberghs work.
