Installation and quickstart 🚀

See the Installation Guide for full instructions on how to install, and the Inference quickstart for a brief introduction on how to run chains. More detailed examples coming soon!

Citing 📚

If you use pbj in your work, please use the DOI 10.5281/zenodo.20048910 and cite the following paper:

• Moretti, C. et al., JCAP12(2023)025, Modified gravity and massive neutrinos: constraints from the full shape analysis of BOSS galaxies and forecasts for Stage IV surveys

For the original implementation and modelling for the real space bispectrum:

• Oddo et al., 2020

For the real space power spectrum and bispectrum:

• Oddo et al., 2021

For the redshift space bispectrum:

• Rizzo et al., 2022

The code has been validated and used to analyse both simulated and real data already in a number of papers, a full list can be found in this ADS library
