## 24 Days of R: Day 16

Yesterday I said that I'd carry on with the monte carlo simulation of insurance data. I'm not going to as I don't think I've got enough time and mental energy to do it justice. I'm sure tens of people are disappointed to learn this. Instead, I'm going to have a look at the recently released

Over the course of the next few days, I'm going to try to find enough time to build up a reasonably simple simulation of insurance exposure and claims. I'll be taking a hierarchical view of the underlying process. As with pretty much everything that I write about, I'm writing about it as I'm learning about

I've had a statistical question that I've wanted to answer for more than 20 years. In college, I often played the strategy game “Axis & Allies” with friends. (Hi Brad, Rob, Brady and Marty!) The game is a crude simulation of the second world war, with various military units available to the player. The player

In this post, I'll look at a very quick way to look at the relationships in a database. I had a bit of fun with my first network graph and plotting the connections between tables and views seems like a natural extension. Here, I'm going to create a bare bones insurance database. We have a

Today, I'm going to finally dip my toe in the water of something I've wanted to do for a long time. I'd wanted to do this with Michael Caine film appearances- and I may yet- but tonight, it'll be a bit simpler. I'm going to draw a network graph, showing the relationship between band members

I don't know how often Michael Caine appeared in a Shakespearean work, but I'm sure that he has and I'm sure that he was excellent. A bit pressed for time today, so just a simple word cloud featuring the full text of King Lear. I found the text at a website that I presume is

How often is someone nominated for an academy award? Who has been nominated most often? Is there a difference between leading and supporting roles? Important questions. To answer them, I'm making use of a list of academy award nominees and winners. I've obtained the data from aggdata.com which has a few sets of free data.

## Creating custom CDF for Affy chips in R / Bioconductor

Creating custom CDF for Affy chips in R / Bioconductor What? For those who don't know, CDF files are chip definition format files that define which probes belong to which probesets, and are necessary to use any of the standard summarization methods such as RMA, and others. Why? Because we can, and because custom definitions have been shown to be quite useful. See...

## Writing papers using R Markdown

Writing papers using R Markdown I have been watching the activity in RStudio and knitr for a while, and have even been using Rmd (R markdown) files in my own work as a way to easily provide commentary on an actual dataset analysis. Yihui has proposed writing papers in markdown and posting them to a blog as a way...

This will be the third time I've tried to write this post. I had started out presuming that I would uncover something fascinating about applying Bayesian inference to a low-frequency claims generation process. That isn't at all what I got and I ought to have known better when I started. I started by doing very
