This repository contains the code used for the paper "Bayesian calibration of stochastic agent based model via random forest". It contains hospitalization and death data produced by the CityCOVID agent based model. It also provides code to train a Random Forest surrogate model for CityCOVID hospitalizations and deaths, calculate a Bayesian estimate of parameters from CityCOVID using this surrogate, and then produce plots and data of this calibration.
All dependencies can be installed by running make install_deps
.
Specifics can be found below.
The code in this repository makes use of the following python
packages:
matplotlib
numpy
pandas
properscoring
pymcmcstat
(from updated version here)seaborn
scikit-learn
These can easily be installed by running make install_python
if you have conda
or pip
already on your system.
Alternatively, they can be installed with pip
via pip install -r requirements.txt
or with conda/mamba
via conda env create -f environment.yml
.
The code in this repository makes use of the following R
packages:
ggdist
coda
mcgibbsit
scoringutils
These can easily be installed by running make install_r
as long as R
is already installed on your system.
Reproduction of the results and plots can most easily be done by running make all_surrogate
followed by make all_calibration
and make compare
.
The above runs various scripts from scripts/
which make use of some utility functions in src/
and data from data/
to output files into results/
and plots into plots/
.
See make help
or make
for more information on individual scripts.
