Mcmc tests in r
WebscapeMCMC v 1.1 1. Is a mixed model right for your needs? A mixed model is similar in many ways to a linear model. It estimates the effects of one or more explanatory variables on a response variable. WebThe most straightforward approach for assessing convergence is based on simply plotting and inspecting traces and histograms of the observed MCMC sample. If the trace of values for each of the stochastics exhibits asymptotic behavior [1] over the last m iterations, this may be satisfactory evidence for convergence.
