Drawing Probability Trees by Hand Is Annoying, So I Built This
Probability trees look simple. You start with an event, add a few branches, write probabilities next to them, and calculate the probability of each path. Easy, right? That was w...

What is the probability that reading this post on probability will increase your willingness to take risks?
We’ve talked about uncertainty in polls (see Margin of Error, Total Margin of Error, Total Margin of Error II) and we’ve talked about ranked data (see exploded logit !). A new pape...
What if the probability distribution underlying your parameter estimation algorithm is the reason you’re getting the wrong answer?Continue reading on Medium »
Probability density function must integrate to 1, and so if you know a density function up to a constant, the constant is determined. When you’re looking at a probability density f...
This came in the mail: My name is ** and I am a junior at ** High School. I am writing to you as a part of a summer assignment for my upcoming research class where I had to choose...

Statistical questions help people investigate patterns rather than look for one fixed answer. Each question anticipates variability: Different people, objects, events, or measureme...
Last week Andrew commented that we need a more transparent workflow for survey statistics. So I looked in the new Bayesian Workflow book: Chapter 19 “Building up to a hierarchical...

I took a look at the above-titled book by economists Duncan Foley and Ellis Scharfenaker. It’s an interesting read, in many ways a throwback to the 1950s when a group of mathematic...
This is genuinely a true story from real life. With a background in Statistics, I will take any and every opportunity to generate, analyse and visualise real-life data... I recentl...
Yesterday, we focused on descriptive statistics — how to summarize the data you already have. But in enterprise data science, the data you…Continue reading on Medium »
Error correcting codes are most simply described in terms of the errors they can certainly correct. For example, the Hadamard code used for the Mariner 9 probe to Mars encoded each...
The mean keeps making its usefulness felt in all sorts of situations, often in truly non-obvious ways The post The Most Beautiful Statistic: The History and the Science of the Humb...
Andrew looped me into an email thread with folks working on poststratification with partial population information. (He knew I’d be interested, see “poststratification without popu...

Beyond the teaching question, this is an interesting topic on its own: thinking about classical statistical ideas of point estimation, hypothesis testing, and uncertainty quantific...
Last week we discussed SynthMargins, a method from the poster Modeling Complex Contingency Tables that uses partial information (margins) about poststratification variables. On the...
