CosmoSlik stands for Cosmology Sampler of Likelihoods.

CosmoSlik is a simple but powerful tool to quickly put together, run, and analyze an MCMC chain for analysis of cosmological data. You can use plugins for things like CAMB, CLASS, the Planck likelihood, other cosmological likelihoods, your own customizations, emcee, etc… It has advantages in ease-of-use, flexibility, and modularity as compared to similar codes like CosmoMC, MontePython, or CosmoSIS.

To get started,


Many of the pages in this documentation are IPython notebooks. If you download the source code, you can run and experiment with any of the examples that you see.
