Autor: Antti J. Kerminen, Shohei Shimizu, Markus Palviainen, Patrik O. Hoyer

Publikováno v: International Journal of Approximate Reasoning. 49(2):362-378

The task of estimating causal effects from non-experimental data is notoriously difficult and unreliable. Nevertheless, precisely such estimates are commonly required in many fields including economics and social science, where controlled experiments

Causal discovery is the task of finding plausible causal relationships from statistical data [1,2]. Such methods rely on various assumptions about the data generating process to identify it from uncontrolled observations. We have recently proposed a

Independent component analysis (ICA) has been extensively studied since it was originated in the field of signal processing. However, almost all the researches have focused on estimation and paid little attention to testing. In this paper, we discuss
