WebMar 13, 2024 · Thus, brms requires the employee to explicitly specify these priors. In the gift example, we used anormal(1, 2) prior on (the population-level intercept of) b1, while we former a normal(0, 2) prior on (the population-level intercept of) b2. Setting priors is a non-trivial job included all kinds of select, especially in non-linear models, so ... WebMay 22, 2024 · Generate data. First, we’ll generate two independent normally distributed samples. These will correspond to two levels of a grouping variable, so let’s call them group A and group B. Group A will have a mean μ A = 20 and a standard deviation σ A = 2, whereas group B have have the parameters μ B = 16 and σ B = 1.5.
