## Text-Based Ideal Points

Published:

The plots below show examples of ideological topics for U.S. Senate speeches (2015-2017) based on the methodology of our paper, Text-Based Ideal Points. Move the slider to see how the ideological topic changes as a function of ideal point:

## Black Box Variational Inference for Logistic Regression

Published:

A couple of weeks ago, I wrote about variational inference for probit regression, which involved some pretty ugly algebra. Although variational inference is a powerful method for approximate Bayesian inference, it can be tedious to come up with the variational updates for every model (which aren’t always available in closed-form), and these updates are model-specific.

## US Senators and PCA

Published:

A couple of weeks ago, I wrote a blog post about modeling ideal points of US senators. I wanted to follow up (very briefly), since I was curious about comparing the Bayesian method there with Principal Component Analysis (PCA).

## Variational Inference for Bayesian Probit Regression

Published:

Variational inference has become one of the most important approximate inference techniques for Bayesian statistics, but it has taken me a long time to wrap my head around the central ideas (and I’m still learning). Since I’ve found that going through examples is the most efficient way to learn, I thought I would go through a single example in this post, performing variational inference on Bayesian probit regression.

## Ideal Points of US Senators

Published:

Popularized by Keith Poole and Howard Rosenthal, ideal point modeling is a powerful way to extract the relative ideologies of politicans based solely on their voting records. A lot has been written on ideal point models, so I’m not going to add anything new, but I wanted to give a brief overview of the Bayesian perspective.

## The Box-Muller Transform

Published:

Every statistician has a favorite way of generating samples from a distribution (not sure if I need a citation for this one). From rejection sampling to Hamiltonian Monte Carlo, there are countless methods to choose from (my personal favorite is rnorm).

## Lies, Damned Lies, and Causal Inference

Published:

To paraphrase Benjamin Disraeli, statistics makes it easy to lie. In this post, I’ll go over an example from Judea Pearl’s excellent textbook, Causality, that shows how different statistical approaches can lead to different estimates of the causal effect of smoking on lung cancer.

## Inauguration Word Clouds with tf-idf

Published:

Trump’s inauguration was yesterday, and we’re all coping with it in different ways. Instead of watching yesterday’s events, I decided to download a bunch of inaugural addresses and make some word clouds (jump ahead a little bit if you’re curious about the more technical details).

## Causal Inference for Genetic Associations

Published:

Recently I’ve become interested in causal inference, as I’ve been exploring both the foundational approaches and the more recent applications to machine learning. An important application is genome-wide association studies (GWAS), where biologists attempt to uncover the causal link between genotypes and traits of interest (i.e. what part of the genome causes orange hair?).

## Betting on Politics with Gaussian Processes

This is the first part of a two-part blog post on Gaussian processes. If you would like to skip this overview and go straight to making money with Gaussian processes, jump ahead to the second part.
