I attended the WOMBAT conference at the zoo last month (WOMBAT – Workshop organised by the Monash Business Analytics Team). As someone interested in R, statistics and data analysis, there was much useful information. There is a nice summary of the WOMBAT workshop by Nicholas Tierney here. The program and and all of the presentations are here.
Highlights for me were:
- Hadley Wickham’s presentation (EDA = visualise + manipulate + model) which has been made into a video. This material is related to Hadley’s forthcoming book, R for Data Science.
- Rob Hyndman’s presentation, Making forecasting easier.
- Christoph Bergmeir’s talk on optimization. One simple take away message was that for everyday optimisation we should stop using optim and start using optimx.
- Nicholas Tierney’s presentation: “Be at Hawk not a Turkey: How a bird’s eye view of your data can streamline data analysis“. Turkey’s spend a lot of time scratching around and I certainly feel like that when dealing with messy datasets. Nicholas has developed some approaches to get an overall view of your data: visdat and ggmissing.
- Andrew Robinson “The joy of text“. Great advice, and examples, on using regular expressions.
Overall it was a really interesting 2 days at a great venue.
