Three tables showing rates of lung cancer among drinkers and non-drinkers, then adjusted for smokers and non-smokers Fox News was excited: " Unplanned children develop more slowly, study finds. " The Telegraph was equally shrill in its headline (" IVF children have bigger vocabulary than unplanned children "). And the British Medical Journal press release drove it all: " Children born after an unwanted pregnancy are slower to develop ." The last two, at least, made a good effort to explain that this effect disappeared when the researchers accounted for social and demographic factors. But was there ever any point in reporting the raw finding, from before this correction was made? I will now demonstrate, with a nerdy table illustration, how you correct for things such as social and demographic factors.

Data.gov.uk has become one of the finest national open data initiatives in the world - it now has more data than the mighty data.gov in the US, with 4,223 datasets, compared to 2,876 over the Atlantic. It's not perfect - far too many links take you to front pages on other sites, rather than the data itself. It could also do with more help for the less-experienced user, witness the multitude of downloads on the Treasury's Combined Online Information System (COINS) dataset ( http://data.gov.uk/dataset/coins ). But nevertheless, what a resource. And where it really comes into its own is in the publication of immense datasets previously kept within the confines of the civil service, many of which show highly local data. So, if I had to pick my top ten data.gov.uk datasets here is where I would start:

Click here to download Visualizing Marathon 2010 Poster. Welcome Visualizing.org is proud to have held the inaugural Visualizing Marathon: a 24-hour student data visualization competition. Inspired by robotics competitions and science fairs, the Marathon was created to give design students an opportunity to collaborate and use design to help tackle real-world issues. It was a fun and intense weekend full of speakers, performances, and of course, the actual competition.Last week, a series of media headlines suggested that immigrants were taking jobs away from British people as the economy enters recovery. These stories were based in part on new ONS statistics, bolstered in some of the papers by reference to a report from MigrationWatch which purported to show that recent immigration to the UK has caused higher unemployment. I wrote here about why these stories were misleading, and explained that the MigrationWatch report had failed to demonstrate the causal link claimed by the headline on its press release ("Immigration has damaged employment prospects for British workers", MigrationWatch press release , 12 August).

Research tips
I have thought quite a lot about including regressors (i.e. covariates) in exponential smoothing ( ETS ) models, and I have done it a couple of times in my published work. See my 2008 exponential smoothing book (chapter 9) and my 2008 Tourism Management paper . However, there are some theoretical issues with these approaches, which have come to light through the research of Ahmad Farid Osman , one of our PhD students at Monash University. Basically, they are never forecastable in the sense explained in Section 10.2 my 2008 book (forecastability is the ETS equivalent of invertibility in ARIMA models).Statistics How To

I worked at the U.S. Naval Research Laboratory for four summers during high school and college. I spent much of my time writing a computer program to do thermal analysis for an experiment that we put on the space shuttle.
