This is the first book to provide a comprehensive introduction to a new
semiparametric causal discovery approach known as LiNGAM, with the
fundamental background needed to understand it. It offers a general
overview of the basics of the LiNGAM approach for causal discovery,
estimation principles, and algorithms.
This semiparametric approach is one of the most exciting new topics in
the field of causal discovery. The new framework assumes parametric
assumptions on the functional forms of structural equations but makes no
assumption on the distributions of exogenous variables other than
non-Gaussianity. It provides data-analysis tools capable of estimating a
much wider class of causal relations even in the presence of hidden
common causes. This feature is in contrast to conventional nonparametric
approaches based on conditional independence of variables.
This book is highly recommended to readers who seek an in-depth and
up-to-date overview of this new causal discovery approach to advance the
technique as well as to those who are interested in applying this
approach to real-world problems. This LiNGAM approach should become a
standard item in the toolbox of statisticians, machine learners, and
practitioners who need to perform observational studies.
