This article uses object-oriented programming to explore of one of the most useful concepts in statistics, distributions. The code is in a Jupyter notebook.You can read a static version of the notebook on nbviewer.ORYou can run the code in a brow...

Yesterday Sanjoy Mahajan and I led a workshop on teaching Bayesian statistics for undergraduates. The participants were college teachers from around New England, including Norwich University in Vermont and Wesleyan University in Connecticut, as w...

In 2011 I wrote an article called "There is Only One Test", where I explained that all hypothesis tests are based on the same framework, which looks like this:Here are the elements of this framework:1) Given a dataset, you compute a test statistic that...

I did a webcast earlier today about Bayesian statistics. Some time in the next week, the video should be available from O'Reilly. In the meantime, you can see my slides here: And here's a transcript of what I said:Thanks everyone for joinin...

Today I am working on another "one-day paper", although this one is a bit of a cheat, since I'm a few hours past the deadline. Nevertheless, the question of the day is whether the Trivers-Willard effect applies to people.According to Wikipedia, t...

This is the fourth part of a series of posts about conditional probability and Bayesian statistics.In the first article, I presented the Red Dice problem, which is a warm-up problem that might help us make sense of the other problems.In the s...

If you read yesterday's post, you know that my colleague Sanjoy Mahajan and I have been working on a series of problems related to conditional probability and Bayesian statistics. In the previous article, I presented the Red Dice problem, which i...

For more than a month, my colleague Sanjoy Mahajan and I have been banging our heads on a series of problems related to conditional probability and Bayesian statistics. We knew when we started that this material is tricky, as demonstrated by veri...

Here's a question that appeared recently on the Reddit statistics forum:If effect sizes of coefficient are really small, can you interpret as no relationship? Coefficients are very significant, which is expected with my large dataset. But coeffic...
