Posterior Draws of a Fitted Ratio Model as a Data Frame

Usage

# S3 method for class 'ratiod_fit'
as.data.frame(x, ...)

Arguments

x

A ratiod_fit object

...

Ignored.

Value

A draws_df data frame: one row per posterior draw, one column per parameter, plus the .chain, .iteration and .draw columns.

Examples

# \donttest{
sim <- sim_ratiod(n = 100, family = ratiod_poisson_gamma(), seed = 1)
fit <- tratio(y_num | y_denom ~ x1 + (1 | group), data = sim$data,
              family = ratiod_poisson_gamma(),
              control = list(iter = 1000, chains = 2, seed = 1))
draws <- as.data.frame(fit)
dim(draws)
#> [1] 1000   19
names(draws)[1:6]
#> [1] "beta_num[1]"   "beta_num[2]"   "beta_denom[1]" "beta_denom[2]"
#> [5] "sigma_re"      "re[1]"        
# }
