Camacho, Faria and Viana 2023 | NEW - "Modelling stellar activity with Gaussian process regression networks" | Gaussian processes and other methods |

Karamanis et al. 2022 | NEW - "Accelerating astronomical and cosmological inference with preconditioned Monte Carlo" | a novel approach to MCMC; code at https://github.com/minaskar/pocomc |

Foreman-Mackey, Agol, Ambikasaran and Angus 2017 | "Fast and Scalable Gaussian Process Modeling with Applications to Astronomical Time Series" | see also https://github.com/dfm/celerite; more advanced version was already presented by M. Mróz |

Tsutomou et al. 2022 | "High Dimensional Statistical Analysis and its Application to ALMA Map of NGC 253" | noise-reduction principal component analysis (NRPCA) and regularized principal component analysis (RPCA) used; suggested by Kasia Małek |

Bryan et al. 2007 | "Mapping the Cosmological Confidence Ball Surface" | |

Importance sampling | The method is very important for speeding-up simulations. Description of the method can be found on-line, or in resources suggested by RP. It would be good to show simple working example. | |

Speagle 2019 | "A Conceptual Introduction to Markov Chain Monte Carlo Methods" | Other concepts are also discussed: importance sampling, effective sample size, approximating posterior integrals with grids |

Vitale 2020 | "One, No One, and One Hundred Thousand -- Inferring the properties of a population in presence of selection effects" | Pedagogical introduction to hierarchical Bayesian inference in presence of selection effects; gravitational waves as an example |

Hogg and Forman-Mackey 2017 | "Data analysis recipes: Using Markov chain Monte Carlo" | Good MCMC introduction that has problems to be solved by the reader; discusses convergence, parametrizations etc. |

LIGO and Virgo 2020 | "Population Properties of Compact Objects from the Second LIGO-Virgo Gravitational-Wave Transient Catalog" | gravitational waves - statistical analysis of O3 run that considers a few different models |

Student project | Student can present what statistical analysis they work on, even if it's not finished. It's likely that other participants will give useful suggestions | |
