 ## Diagnosing Pathfinder
 
 Pathfinder diagnoses the accuracy of the approximation by computing the density ratio of the true posterior and

 ## Using Pathfinder for initializing MCMC

 very likely better for initializing MCMC than random draws from an arbitrary pre-defined distribution (e.g. uniform from 
 -2 to 2 used by Stan by default). If Pareto-$\hat{k}$ is larger than 0.7, it is likely that one of the ratios is much bigger
