Causal Analysis in Theory and Practice

Spring Greeting from the UCLA Causality Blog

Filed under: Announcement — bryantc @ 3:13 am

Dear friends in causality research,
This Spring Greeting from UCLA Causality blog contains:
A. News items concerning causality research,
B. New postings, new problems and some solutions.

The American Statistical Association (ASA) has announced recipients of the 2016 “Causality in Statistics Education Award”.
Congratulations go to Onyebuchi Arah and Arvid Sjolander who will receive this Award in July, at the 2016 JSM meeting in Chicago.
For details of purpose and selection criteria, see

I will be giving another tutorial at the 2016 JSM meeting, titled “Causal Inference in Statistics: A Gentle Introduction.”
Details and Abstract can be viewed here:

A3. Causal Inference — A Primer
For the many readers who have inquired, the print version of our new book “Causal Inference in Statistics – A Primer” is now up and running on Amazon and Wiley, and is awaiting your reviews, your questions and suggestions. We have posted a book page for this very purpose, which includes selected excerpts from each chapter, errata and updates, and a sample homework solution manual.

The errata page was updated recently under the diligent eye of Adamo Vincenzo. Thank you Adamo!

The Solution Manual will be available for instructors and will incorporate software solutions based on a DAGitty R package, authored by Johannes Textor.  See

Vol. 4 Issue 2 of the Journal of Causal Inference (JCI) is scheduled to appear in September 2018. The current issue can be viewed here: My own contribution to the current issue discusses Savage’s Sure Thing Principle and its ramifications to causal reasoning.

As always, submissions are welcome on all aspects of causal analysis, especially those deemed foundational. Chances of acceptance are inversely proportional to the time it takes a reviewer to figure out what problem the paper attempts to solve. So, please be transparent.

Recollections from the WCE conference at Stanford.

On May 21, Kosuke Imai and I participated in a panel on Mediation, at the annual meeting of the West Coast Experiment Conference, organized by Stanford Graduate School of Business.

Some of my recollections are summarized on our Causality Blog here:

B2. Generalizing Experimental findings
In light of new results concerning generalizability and selection bias, our team has updated the “external validity” entry of wikipedia. Previously, the entry was all about threats to validity, with no word on how those threats can be circumvented. You may wish to check this entry for accuracy and possible extensions.

B3. Causality celebrates its 10,000 citations
According to Google Scholar,, my book Causality (Cambridge, 2000, 2009) has crossed the symbolic mark of 10,000 citations. To celebrate this numerological event, I wish to invite all readers of this blog to an open online party with the beer entirely on me. I dont exactly know how to choreograph such a huge party, or how to make sure that each of you gets a fair share of the inspiration (or beer). So, please send creative suggestions for posting on this blog.

On a personal note: I am extremely gratified by this sign of receptiveness, and I thank readers of Causality for their comments, questions, corrections and reservations which have helped bring this book to its current shape (see

  1. Hal Varian was kind enough to send us the first workable model for the online beer party.
    Here it is:

    An Irish man walks into a pub. The bartender asks him, “What’ll you have?” The man says, “Give me three pints of Guinness please.” So the bartender brings him three pints and the man proceeds to alternately sip one, then the other, then the third until they’re gone. He then orders three more. The bartender says, “Sir, I know you like them cold. You don’t have to order three at a time. I can keep an eye on it and when you get low, I’ll bring you a fresh cold one.” The man says, “You don’t understand. I have two brothers, one in Australia and one in the States. We made a vow to each other that every Saturday night we’d still drink together. So right now, my brothers have three Guinness Stouts too, and we’re drinking together. The bartender thought that was a wonderful tradition. Every week the man came in and ordered three beers. Then one week he came in and ordered only two. He drank them and then ordered two more. The bartender said to him, “I know what your tradition is, and I’d just like to say that I’m sorry that one of your brothers died.” The man said, “Oh, me brothers are fine—-my doctor just told me to quit drinking.”
