WebIf you want to get those WAIC weights, you can use the brms::model_weights() function like so: model_weights (b6. 11, b6. 12, b6. 13, b6. 14, weights = "waic") %>% round (digits = 2) ## b6.11 b6.12 b6.13 b6.14 ## 0.02 0.01 0.02 0.96. That last round() line was just to limit the decimal-place precision. If you really wanted to go through the ... WebJul 16, 2015 · Leave-one-out cross-validation (LOO) and the widely applicable information criterion (WAIC) are methods for estimating pointwise out-of-sample prediction accuracy from a fitted Bayesian model using the log-likelihood evaluated at the posterior simulations of the parameter values.
