smsharma/eft-hod

Simulation-based priors connecting EFT of large-scale structure and halo occupation distribution (HOD) models.

Simulation-based priors connecting EFT and HOD models

Used in "Full-shape analysis with simulation-based priors: constraints on single field inflation from BOSS" by Ivanov, Cuesta-Lazaro, Mishra-Sharma, Obuljen, and Toomey.

Requirements

Install from requirements.txt or simply do

pip install torch numpy tqdm corner matplotlib nflows scipy

Usage

Train density estimators in notebooks/01_eft_fit.py, sampling from priors and log-density calculation in notebooks/02_usage.py.
