Statistical modelling and analysis of big data

There is a one day workshop on this topic on 23 February 2015 at QUT in Brisbane. I will be speaking on “Visualizing and forecasting big time series data”. OVERVIEW Big data is now endemic in business, industry, government, environmental management, medical science, social research and so on. One of the commensurate challenges is how to […]

A Tennis Match Graphic

I know you're not thinking about tennis in December (at least those of you north of the equator). I'm generally not either. But this post is really about graphics, and I may have something that will interest you. And remember, the Australian Open and t...

Visualization of probabilistic forecasts

This week my research group discussed Adrian Raftery’s recent paper on “Use and Communication of Probabilistic Forecasts” which provides a fascinating but brief survey of some of his work on modelling and communicating uncertain futures. Coincidentally, today I was also sent a copy of David Spiegelhalter’s paper on “Visualizing Uncertainty About the Future”. Both are […]

Unknown pleasures

Have I missed unknown pleasures in Python by focusing on R? A comment on my blog post of last week suggested just that. Reason enough to explore Python a little. Learning another computer language is like learning another human language - it takes time...

Make your own hotly criticised circle graph!!!

Make your own hotly criticized circle graph! The recent critical post on R-bloggers has got me wanting to make my own bubble graphs despite the popular criticism of the graph. After some attempts I have produced something that looks similar but needs s...

Car crash stats revisited: My measurement errors

Last week, I created revised versions of graphs of car crash statistics by state (including an interactive version), from a post by Mona Chalabi at 538. Since I was working on those at the last minute in the middle of the night, to be included as an example in a lecture on creating effective figures […]

Interactive plot of car crash stats

I spent the afternoon making a D3-based interactive version of the graphs of car crash statistics by state that I’d discussed yesterday: my attempt to improve on the graphs in Mona Chalabi‘s post at 538. See it in action here. Code on gith...

Improved graphs of car crash stats

Last week, Mona Chalabi wrote an interesting post on car crash statistics by state, at fivethirtyeight.com. I didn’t like the figures so much, though. There were a number of them like this: I’m giving a talk today about data visualization [slides | github], and I thought this would make a good example, so I spent […]

Waterfall and 3D plotting exploration

Taking the very cool 'waterfall graph' code posted by Robert Grant I have added some features (resistance to distributions with sparse data at some areas) as well as the ability to heat map the bivariate distribution based on a third variable z. Find t...

A new candidate for worst figure

Today I read a paper that had been submitted to the IJF which included the following figure along with several similar plots. (Click for a larger version.) I haven’t seen anything this bad for a long time. In fact, I think I would find it very difficult to reproduce using R, or even Excel (which […]
