SimpleMC workshop (2 days)

Oficial GitHub repo: https://github.com/ja-vazquez/SimpleMC

Docs: https://igomezv.github.io/SimpleMC/index.html#

Requirements

  • A computer, Internet conection and a Google account (to use google colab).
  • Otherwise, you must install the dependecies from requirements_full.txt. You can use pip3 install -r requirements_full.txt.

For didactic purposes, we recommend Google Colab, a free Google service to run notebooks in the cloud, allowing to use Python 2 or Python 3 with CPU, GPU and TPU. Only a Google account is required. SimpleMC is coded in Python 3.

You can find this repo from Google Colab, open it and make a copy to save your changes to Google Drive. You also can clone or download this repository and run the notebooks locally or in Google Colab.


Workshop outline

Day 1

  • Overview of Bayesian inference and parameter estimation
  • Introduction and installation of SimpleMC.
  • First examples in SimpleMC:
    • CosmoCalc
    • Optimizers.

Day 2

  • Review for Day 1.
  • Bayesian inference.
  • Using an ini file (exercise).
  • Model comparison (exercise).
  • New models.
    • Without cosmology.
    • Based on LCDM.
  • New datasets (optional, exercise).
