Suppose you have statistical data that too many dimensions, in other words too many variables of the same random process, that has been observed many times. You want to find out, from all these variables (or all these dimensions when speaking in terms of multivariate data ...

General relativity, quantum physics, freely-falling planes and Bayesian statistics

We’re famous: the work that concluded my PhD is now picked up by the press http://www.physorg.com/news179481148.html

I hadn’t realized before reading this journalist’s version of the story, but we have all the proper buzz words:

  • quantum physics
  • freely-falling planes
  • Bayesian ...

Acceleration estimation in atom-interferometric tests of the Einstein equivalence principle

Hurray! The pivot article that marks my transition from physics to statistic modeling is finally out:

How to estimate the differential acceleration in a two-species atom interferometer to test the equivalence principleG Varoquaux, R A Nyman, R Geiger, P Cheinet, A Landragin and P Bouyer
