The 1st tests from a north German farm suspected of being the source
of an _E. coli_ [O104:H4] outbreak are negative, officials say. Of 40 samples from the farm being examined, they said 23 tested negative.

For anyone who hasn't been paying close attention to what's happening across the pond, there's an ongoing outbreak of enterohemorrhagic E. coli (EHEC)--the type of E. coli that includes O157:H7, which has been associated with outbreaks of disease associated with food. The most infamous outbreak was the 1993 Jack-in-the-Box disaster, associated with undercooked hamburgers contaminated with the organism, but there have also been outbreaks associated with contaminated vegetables (such as…
tlambert | February 26, 2009This post contains some more notes on a reply to the badly flawed "Main Street Bias" paper.
In my previous post I showed that the MSB papers was wrong to claim that it was plausible that the unsampled regions was 10 times as large as the sampled region. In this post I look at their model. Their model is wrong because it assumes that there is no main street bias in the sampled region and because of this they massively overestimate any bias in the Lancet sampling.
Let's start with a correct model of the situation. I've adopted their terminology where possible.
We have a population of size N…
