Meta-Analysis: A Structural Equation Modeling Approach

Acknowledgments

I thank Wai Chan, my former supervisor, for introducing me to the exciting field of structural equation modeling (SEM). He also suggested me to explore meta-analytic structural equation modeling in my graduate studies. I acknowledge the suggestions and comments made by many people: Shu-fai Cheung, Adam Hafdahl, Suzanne Jak, Yonghao Lim, Iris Sun, and Wolfgang Viechtbauer. All remaining errors are mine. I especially thank my wife for her support and patience. My daughter was born during the preparation of this book. I enjoyed my daughter's company when I was writing this book. Part of the book was completed during my sabbatical leave supported by the Faculty of Arts & Social Sciences, the National University of Singapore. I also appreciate the funding provided by the Faculty to facilitate the production of this book. I thank Heather Kay, Richard Davies, Jo Taylor, and Prachi Sinha Sahay from Wiley. They are very supportive and professional. It has been a pleasure working with them.

The metaSEM package could not be written without R and OpenMx. Contributions by the R Development Core Team and the OpenMx Core Development Team are highly appreciated. Their excellent work makes it possible to implement the techniques discussed in this book. I have to specially thank the members of the OpenMx Core Development Team for their quick and helpful responses in addressing issues related to OpenMx. I also thank Yves Rosseel for answering questions related to the lavaan package. ...
