WebThe Bayesian model adds priors on the regression coefficients (in the same way as stan_glm) and priors on the terms of a decomposition of the covariance matrices of the group-specific parameters. See priors for more information about the priors. The stan_lmer function is equivalent to stan_glmer with family = gaussian (link = "identity").
