Creating your personal, portable R code library with GitHub

An animated peek into the workings of Bayesian Statistics

One of the practical challenges of Bayesian statistics is being able to deal with all of the complex probability distributions involved. You begin with the likelihood function of interest, but once you combine it with the prior distributions of all the parameters, you end up with a complex posterior distribution that you need to characterize. Since you usually can't...

Visualizing optimization process

One of the approaches to graph drawing is application of so called force-directed algorithms. In its simplest form the idea is to layout the nodes on plane so that all edges in the graph have approximately equal length. This problem has very intuitive ...

Warrior Zombies from Outer Space II: Mayhem Unleashed

Given the speed at which I consume them, it's only justified that the first post on this blog is about movies. (Although, by that logic, it could have equally well been about sandwiches, Nutella, or tissue paper. Note to self: Look for a Nutella consumption dataset) Anyway, this post is about movie taglines - specifically, the words that...
