Back to Normal – Box-Cox Transformations in Cosmology
If you have a question about this talk, please contact David Titterington.
Box-Cox transformations are a widely used Gaussianisation tool in various research areas, which has received little attention in astrophysics so far. I am going to present two recent cosmological applications of Box-Cox transformations. They were used to Gaussianise the weak lensing projected mass distribution, as a generalisation of the currently en-vogue logarithmic transformations, with the goal of maximising the information contained in two-point statistics. Moreover I will present work on the generalisation of Fisher matrices by means of Box-Cox transformations in order to produce predictions of arbitrary posterior distributions and discuss the potential of this ansatz to construct statistically independent parameter sets for arbitrary inference problems.
