One informal analysis suggests short first names are strongly correlated with higher salaries. They are bad in several ways, and modern glyphs are little better. For example, v and w, or m and n.
Business Week recently ran an spoof article pointing out some amusing examples of the dangers of inferring causation from correlation. The standard scientific answer to this question is that with some caveats we can infer causality from a well designed randomized controlled experiment.
And, given that we can find more general procedures for inferring causal relationships, what does causality mean, anyway, for how we reason about a system? It might seem that the answers to such fundamental questions would have been settled long ago.
In fact, they turn out to be surprisingly subtle questions. Over the past few decades, a group of scientists have developed a theory of causal inference intended to address these and other related questions. This theory can be thought of as an algebra or language for reasoning about cause and effect.
Many elements Process directional essay the theory have been laid out in a famous book by one of the main contributors to the theory, Judea Pearl. Although the theory of causal inference is not yet fully formed, and is still undergoing development, what has already been accomplished is interesting and worth understanding.
In this post I will describe one small but important part of the theory of causal inference, a causal calculus developed by Pearl. This causal calculus is a set of three simple but powerful algebraic rules which can be used to make inferences about causal relationships.
The post is a little technically detailed at points. However, the first three sections of the post are non-technical, and I hope will be of broad interest.
You may find it informative to work through these exercises and problems. Before diving in, one final caveat: I am not an expert on causal inference, nor on statistics.
The reason I wrote this post was to help me internalize the ideas of the causal calculus. Occasionally, one finds a presentation of a technical subject which is beautifully clear and illuminating, a presentation where the author has seen right through the subject, and is able to convey that crystalized understanding to others.
