{title:Syntax}

{p 8 18 2}
{cmd:midas bayesplot}

{title:Description}

{pstd}
{cmd:midas bayesplot} displays convergence diagnostic plots for the MCMC
chains from {cmd:midas mh} or {cmd:midas hmc}. Four panels are produced:

{phang2}(1) {bf:Trace plots} -- chain values by iteration for each parameter.{p_end}
{phang2}(2) {bf:Density plots} -- posterior density of each parameter.{p_end}
{phang2}(3) {bf:Autocorrelation plots} -- ACF of the chain to assess mixing.{p_end}
{phang2}(4) {bf:Running mean plots} -- cumulative mean convergence.{p_end}

{pstd}
Must follow {cmd:midas mh} or {cmd:midas hmc}. Not available after
{cmd:midas mle}, {cmd:midas qrsim}, or {cmd:midas inla}.
