A causation coefficient and taxonomy of correlation/causation relationships
نویسنده
چکیده
This paper introduces a causation coefficient which is defined in terms of probabilistic causal models. This coefficient is suggested as the natural causal analogue of the Pearson correlation coefficient and permits comparing causation and correlation to each other in a simple, yet rigorous manner. Together, these coefficients provide a natural way to classify the possible correlation/causation relationships that can occur in practice and examples of each relationship are provided. In addition, the typical relationship between correlation and causation is analyzed to provide insight into why correlation and causation are often conflated. Finally, example calculations of the causation coefficient are shown on a real data set.

Towards Sound HTTP Request Causation Inference
Network traces are a useful tool in understanding how users navigate the web. Knowing the sequence of pages that led a user to arrive at a malicious website can help researchers develop techniques to prevent users from reaching such sites. Nevertheless, inferring sound causation between HTTP requests is a challenging task. Previous work often inferred these relationships without proper calibrat...
متن کاملThe Randomized Causation Coefficient
We are interested in learning causal relationships between pairs of random variables, purely from observational data. To effectively address this task, the state-of-the-art relies on strong assumptions on the mechanisms mapping causes to effects, such as invertibility or the existence of additive noise, which only hold in limited situations. On the contrary, this short paper proposes to learn h...

متن کاملCausal Relationships and Relationships between Levels: The Modes of Description Perspective
Many researchers have argued for a description of nature using multiple levels, or modes of description, as we call them. This paper focuses on a confusion that follows from the multiple-mode approach, a confusion due to the notion of causation between modes. Causation between modes is reinterpreted as ordinary causation but with cause and effect described in different modes. In the first part ...
