If you have a question about this talk, please contact Ilya Mandel. Astrophysics and cosmology have increasingly become data driven with the availability of large amount of high quality data from missions like WMAP , Planck and LHC . This has resulted in the development of many innovative methods for performing robust statistical analyses. MultiNest is a Bayesian inference algorithm, based on nested sampling, which has been applied successfully to numerous challenging problems in cosmology and astroparticle physics due to its capability of efficiently exploring multi-modal parameter spaces. MultiNest can also calculate the Bayesian evidence and therefore provides means to carry out Bayesian model selection. I will give a brief description of this algorithm and review its applications in astrophysics and cosmology. I will also describe some recent work on developing new methods for greatly accelerating statistical analyses, in particular by combining neural networks and nested sampling methods.
