 be a valid R expression using Delta_WAIC and/or SE_Delta_WAIC (e.g., "Delta_WAIC &gt; 2 &amp; Delta_WAIC - SE_Delta_WAIC &gt; 0"). For method "DIC", <code>winning_criteria</code> must be a numeric value. For method "PMP", the winning criteria should be a numeric value between 0 and 1 (default value = 0.75). This sets the threshold value for which the posterior probability of the more complex model, given the data, in each model comparison must exceed to be declared the more appropriate model. In all cases,
