model <- bsm_ng(drownings[, "deaths"], u = drownings[, "population"],
  xreg = drownings[, "summer_temp"], distribution = "poisson",
  beta = normal(0, 0, 1),
  sd_level = gamma_prior(0.1,2, 10), sd_slope = gamma_prior(0, 2, 10))

fit <- run_mcmc(model, iter = 5000,
  output_type = "summary", mcmc_type = "approx")
