A presentation on Bayesian hierarchical modeling

This is a slide deck that I put together for my day job. It explains Bayesian hierarchical modeling. Bayesian hierarchical modeling (slide deck) Bayesian hierarchical modeling (pdf) It's given in the context of A/B testing and multiple comparisons, and assumes some knowledge of Beta distributions - but even if you don't have that background, it […]

My facebook post on Easter

This is a copy of my post on Facebook, which I put up on Easter. It is here as a fixed-link reference for my friends who don't frequent Facebook. The $10,000 offer is currently only open to my personal friends. But I do want all of my readers to know what's going on with my […]

Bayesian evaluation for the likelihood of Christ's resurrection (frozen copy)

This was the state of the "Bayesian evaluation for the likelihood of Christ's resurrection" post, as of Easter 2018, in the "second draft" form. Some of the formatting has been lost in the blog migration, particularly in the Jupyter notebooks, but the content has been retained. This post will remain unchanged, while the other post […]

Reflections on the upcoming solar eclipse

I'm releasing this post a few days earlier than usual, as I'll be on the road trip for this eclipse at the regularly scheduled posting time. Also, this post has been cross-posted on my church's blog. God will do something great and marvelous on August 21, 2017: there will be a total eclipse of the […]

Some vague, unoriginal thoughts about the election

[...] Surely the nations are like a drop in a bucket; they are regarded as dust on the scales; he weighs the islands as though they were fine dust. Lebanon is not sufficient for altar fires, nor its animals enough for burnt offerings. Before him all the nations are as nothing; they are regarded by […]

Finding pi in a square grid: or, why you can have square brownies for pi day

This is a picture I took on the side of a road: The trees are planted in a regular pattern, in basically square grids. This creates the fascinating picture you see when you then look at the trees from the sides. You can see far off into the distance along some angles, but are blocked […]

On martyrdom (Part 5)

(This is a continuation of the last week's post.) That is why we must occasionally speak of martyrdom: we need to know what we're spending our lives on. We need to know what we're living for. And that must necessarily be something we're also willing to die for. For to live for something is a […]

On martyrdom (Part 4)

The American church seems squeamish about discussing martyrdom. I'm not quite sure why that is, but if I had to guess, I might say that it's a combination of the following reasons: 1. The American church is very comfortable - being that it's in a Christian-majority country with a great deal of wealth and power. […]

On martyrdom - the value of a human life (part 3)

A human life is worth about 10 million dollars. That is the market rate for an American life. In other parts of the world - say, sub-Saharan Africa, where malaria is widespread, the value of a human life is less - only about $3000. I know this, because I could save such a life for that […]
