Extending the well-known book of Little and Rubin,(3) Missing Data in Clinical Studies puts a special emphasis on real-life case studies. Chapters 5, 6, 13, 25 and 26, among other, are dedicated to such practical case analysis.
Overall, this book provides an interesting discussion about potential design considerations that should be considered in order to mitigate patients from dropping out of a clinical study. Though some influential information might be missing in the pattern of individual responses, it is always better to take time to consider the imputation solution. In addition, the concept of missing-data mechanism is discussed along several chapters. Five general strategies of handling missing data are presented:
- Complete-case analysis
- Weighting methods
- Imputation methods
- Analysing data as incomplete-
- Other methods
Special mechanisms to missingness (MNAR, MAR) as well as the kind of data (continuous and/or discrete, latent class, etc.) at hand are all handled with the same systematic approach. Analyses are carried out using the SAS Software, through some incursion into other statistical package can also be found in the book.
I have hacked the complete Table of Contents, using shell scripts and emacs, as I cannot found it in a PDF decent format on the web, nor on Wiley’s website. So, don’t pay attention to TOC page numbers which do not reflect actual content of the book. However, Wiley offers pdf excerpts for Chapter 1 and Index, see j.mp/dkG9aJ.
