Colour wheels in R

5 November 2011

Regular readers will know I use the R package to produce most of the charts that appear here on the blog. Being more quantitative than artistic, I find choosing colours for the charts to be one of the trickiest tasks when designing a chart, particularly as R has so many colours to choose from. In [...]

Melbourne Cup

1 November 2011

I have been resting on my laurels for too long. Two years ago I had Shocking success tipping a winner for the Melbourne Cup. Needless to say the analysis was entirely bogus, but it was fun. Since then I have been reluctant to tarnish my spotless prediction record, but fortune favours the brave, so I [...]

The oldest bank in the world

29 October 2011

Yes I am back. I know it has been a while. What can I say? I have been quite busy! One of the things taking up my time during the week was preparing for and then giving a talk for the Q-Group on operational risk capital modelling. It sounds arcane, I know, but there was [...]

What will the Reserve Bank do this week?

3 October 2011

It has been a while since I have had a Reserve Bank poll here on the Mule. The Bank will be sitting down on Tuesday to decide whether or not they should adjust monetary policy. Westpac chief economist, Bill Evans, was the first of the bank economists to start predicting that the next move in [...]

Ring-fencing rogue traders

25 September 2011

Kweku Adoboli managed to cost UBS over $2 billion with his rogue trading, and has now cost chief executive Oswald Grübel his job. While this time the buck stopped at the top, it is more than can be said for many previous rogue trading cases. Grübel was called out of retirement to take the helm [...]

Unblock Us

18 September 2011

A few months ago, I complained that more and more online music sites have blocked access from Australia. Of course, the arcane licensing of intellectual property has also led to many other sites being blocked for Australians. Anyone living down under trying to access BBC TV via their iPlayer, or trying to stream US TV [...]

Dissonance and Debt

1 September 2011

Ever since Standard & Poor’s downgraded the US government from AAA to AA+ I have been drawn into debates about the risks posed by growing US government debt. Ever since reading the book Mistakes Were Made by Carol Tavris and Elliot Aronson I have been fascinated by cognitive dissonance and as my debt debates kept following the same [...]

Off the rails: mag-lev personal rapid transit

21 August 2011

I have not been thinking about blog posts much over the last week and a half: on the 11 August my closest friend died and his memorial service was a week later. However, I have received a guest post from a new contributor to the Stubborn Mule: Norwegian academic Trond Andresen from the Norwegian University of [...]

Train in vain

4 August 2011

James Glover is a regular contributor to the Stubborn Mule who tries, whenever possible, to incorporate back of the beer coaster calculations in his posts. Here his beer coaster helps him skewer the prospects of high speed rail in Australia. Don’t get me wrong–I love trains. I have caught trains around Europe and even the [...]

Currencies punching above their weight

24 July 2011

I recently enjoyed lunch with a group of former colleagues. At one point, the conversation turned to the Australian dollar, a natural enough topic for a bunch of finance types. Someone observed that the Aussie is the 5th most actively traded currency in the world, which is impressive since Australia is certainly not the 5th [...]
