First steps

• Requirements
• Quickstart
• Customize ini file

After proper installation of the requirements, generally speaking, the steps to run SimpleMC are as follows: 1) configure an ini file, 2) read this in a Python script, 3) run in terminal, and 4) analyze outputs.

The output chains of Bayesian inference algoritms (MCMC and nested sampling) are text files that have the same structure as the CosmoMC chains consisting in:

• First column.- weights of the sampling method.

• Second column.- log-likelihood function.

• Third to N+2 columns.- N free parameters of the cosmological model under analysis.

• Last columns.- log-likelihood function per each type of data and derived parameters.

In addition, two other output files are generated: a summary and a .paramnames file with the names of the free parameters of the cosmological model.
