Logistic regression: moving from significant results to meaningful insight

Association studies are a favourite tool for geneticists to understand the genetics that determine our health. It is simply routine now to test every mutation amongst your patients for association with a given trait (for example BMI or breast cancer).

Clustering Gene Expression Data: adding layers to a heatmap

So you have some data, perhaps a lot of data, but you’re not quite sure what to do with it… where do you start? Is it interesting data? Would it tell a good story, or just be a confusing mess?  This

Databases for finding human protein-coding genes

After approx. 4 months with the Merriman group, I am beginning to get a handle on how they operate and the typical questions that they are interested in. At a very high level, a typical workflow might involve finding interesting

Visualising Data in 3 Dimensions

I came across this brilliant cheat sheet for picking a visualisation for you data: ExtremePresentation – Choosing a Good Chart. Of course these are static visualisations, but the same principals would hold for interactive visualisation. What I find interesting, is
