Generating an academic CV with R and YAML

March 6, 2015 | James Keirstead

Follow Email For the past couple years, I’ve been using Kieran Healy’s lovely template for my academic CV. Kieran’s code is a customised *.tex file which, of course, has the virtue of simplicity. All a person needs to do is update it with glorious achievements from time ... [Read more...]

Waterfall plots in R

February 18, 2015 | James Keirstead

Follow Email Last week I posted about an orphaned paper of mine, a piece of research that hasn’t yet found a home and which I’m unlikely to find further time to work on. Abandoning something that you’ve worked hard on is disappointing and so it made sense ... [Read more...]

Fumbling fumble statistics

January 30, 2015 | James Keirstead

Follow Email I wanted to add my two-cents worth to the “Deflate-gate” statistics row that’s been going on recently. If you want to catch up with the story, then you should start with the original articles at Sharp Football Analysis (1, 2) and this critique by Gregory J. Matthews and Michael ... [Read more...]

Success rates for EPSRC proposals

December 12, 2013 | James Keirstead

Email In my last post, I looked at the success rates for EPSRC Fellowship applications using funnel plots. As luck would have it, Alex Hulkes and Derek Gillespie from EPSRC then got it touch to say that they had done a similar internal analysis and would I be interested in ... [Read more...]

Success rates for EPSRC Fellowships

November 18, 2013 | James Keirstead

Email I was recently at a presentation where the success rates for EPSRC fellowships were given by theme. The message of the talk was that Engineering fellowships were under-subscribed and so we should all be preparing our applications. But just because a theme is under-subcribed doesn’t mean that you’... [Read more...]

New R package: scholar

October 23, 2013 | James Keirstead

My new R package, scholar, has just been posted on CRAN. The scholar package provides functions to extract citation data from Google Scholar. In addition to retrieving basic information about a single scholar, the package also allows you to compare multiple scholars and predict future h-index values. There’s a ... [Read more...]

We NEED more data

November 22, 2012 | James Keirstead

Email One of the historic difficulties of doing research on urban energy systems has been the limited availability of data at sufficiently detailed spatial resolutions. Without this data, you might end up relying on aggregate information about the built environment, building occupants, and local geography that doesn't apply to the ... [Read more...]

Gaussian process regression with R

April 5, 2012 | James Keirstead

I’m currently working my way through Rasmussen and Williams’s book on Gaussian processes. It’s another one of those topics that seems to crop up a lot these days, particularly around control strategies for energy systems, and thought I should be able to at least perform basic analyses ...

November 15, 2011 | James Keirstead

I’ve been working through Gelman et al.’s otherwise excellent Bayesian Data Analysis and it’s going reasonably well. My statistics is a little bit rusty so it’s taken time to work through all of the exercises and really understand what’s going on. But I say “otherwise ... [Read more...]

Getters and setters in R

August 12, 2011 | James Keirstead

Tweet When I first started using R, one of the things that attracted me was its claim to be an object-oriented programming (OOP) language. Coming from a Java background, I was used to designing software with OOP concepts like encapsulation and inheritance but, when I turned my hand to R, ... [Read more...]

Positive coefficient regression in R

August 5, 2011 | James Keirstead

Ever have a regression model where the coefficients don't make sense? I've been trying to predict electricity and gas consumption from daily activity schedules but a simple linear regression kept saying that demands should go down the more an activity is performed. Fortunately I found the nnls package and show ... [Read more...]

Changing the fonts in R plots

October 28, 2007 | James Keirstead

Tweet I use R to do almost all of my statistical analysis and plotting. It has a very steep learning curve but once you get into it, it’s very powerful and you can customise almost anything. The only problem is that these changes are not always obvious or easy ...
