发散跃迁

1: 预热后出现 15 次发散跃迁。将 adapt_delta 提高到
0.8 以上可能有帮助。

stan_model <- stan_glm(popularity ~ song_age, data = songs,
  control = list(adapt_delta = 0.95))

stan_model <- stan_glm(popularity ~ song_age, data = songs,
  control = list(adapt_delta = 0.99))

链 1 达到最大树深度

stan_model <- stan_glm(popularity ~ song_age, data = songs,
  control = list(max_treedepth = 10))

stan_model <- stan_glm(popularity ~ song_age, data = songs,
  control = list(max_treedepth = 15))
