For no reason in particular, I'm curious what the expected number of feet you would have to walk to find the nearest road is, starting from a random point on the world, facing a random direction.

Hi, I'm processing data from a harddisk from one large file (processing is fast and not a lot of overhead) and then have to write the results back (hundreds of thousands of files). I started writing the results straight away in files, one at a time, which was the slowest option. I figured it gets a lot faster if I build a vector of a c...

Say I had some data, for which I want to fit a parametrized model over it. My goal is to find the best value for this model parameter. I'm doing model selection using a AIC/BIC/MDL type of criterion which rewards models with low error but also penalizes models with high complexity (we're seeking the simplest yet most convincing explanat...
I am gathering data from a website. I estimate to get 10.000 datapoints (time - value) multipled by seven - over time. That is way to much. Both for storing and plotting it in a real time alike graph (through jQuery flot). I'm looking for a text dealing with this sort of problems. To be more precise: algorithms, statistical math for find...
