From: Spatial analysis of MODIS aerosol optical depth, PM2.5, and chronic coronary heart disease
Trace plots of the 80,000 Markov Chain Monte Carlo (MCMC) updates. Simulation trace plots for the intercept and the effect of PM2.5 on chronic coronary heart disease from the Bayesian hierarchical model with a convolution prior. Horizontal axis represents iteration number and vertical axis represents simulated parameter value. The red trace is for one Markov chain, and the blue for the other.
