Some heuristics about local regression and kernel smoothing

In a standard linear model, we assume that . Alternatives can be considered, when the linear assumption is too strong. Polynomial regression A natural extension might be to assume some polynomial function, Again, in the standard linear model approach (with a conditional normal distribution using the GLM terminology), parameters can be obtained using least squares, where a regression of...

Creating your personal, portable R code library with GitHub

As I discussed in a previous post, I have a few helper functions I’ve created that I commonly use in my work. Until recently, I manually included these functions at the start of my R scripts by either the tried and true copy-and-paste method, or by extracting them from a local file with the <code>source()</code> function. The former approach...

Real Pirate Attacks, Charted with R

To mark Talk Like a Pirate Day, Bob Rudis uses R to animate a map of the cumulative real-world pirate attacks since 1978: Looks like the Carribean and the West Indes, traditional pirate haunts, are still active. But the real hot-spot in modern times is Africa. Find the R code behind the animation at the blog post linked below....

Animated IRL Pirate Attacks In R

Avast me hearRties! (ok, enough of the pirate speak in a blog post) It wouldn’t be TLAPD without out some modest code & idea pilfering from Mark Bulling & Simon Raper. While those mateys did a fine job hoisting up some R code (your really didn’t think I’d stop with the pirate speak, did you?)

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...
