WebIn addition, the linear mixed model reflecting only the random intercept can be calculated as 1826.423 based on the Bayes information criterion. In addition, the linear mixed model that reflects both the random intercept and the slope is calculated as 1530.467, so it can be judged that the model fit is higher than the model that reflects only the random intercept.
