CosmoSIS Parameter Estimator
Purpose
Provides expert guidance on CosmoSIS for cosmological parameter estimation, including modular likelihood construction and MCMC sampling.
Capabilities

- Multiple sampler support (emcee, multinest, polychord)
- Prior specification
- Chain analysis and diagnostics
- Plotting and visualization
- Pipeline construction
Usage Guidelines
- Pipeline Setup: Configure modular analysis pipeline
- Likelihoods: Build likelihood functions from data
- Priors: Specify parameter priors
- Sampling: Run MCMC with appropriate sampler
- Analysis: Analyze chains and compute posteriors
