The results presented in our paper represent the first attempt at describing population … WebThe formalism is convenient to be applied in numerical computations, and therefore it is currently widely used in cosmological parameter estimation. However, the Fisher matrix formalism has its limitations in under- or overestimating the errors in certain situations. In this paper we will try to investigate these misestimations. 2 Statistics ...
WebForecasting Constraining Power with the Fisher Formalism To forecast errors on a set of cosmological parameters, θ → , we make use of the Fisher matrix formalism. This formalism provides constraints on θ → under the assumption that the likelihood is approximated by a multivariate Gaussian distribution.
