# S3 method for class 'gam'
theta(object, transform = TRUE, ...)

Arguments

object: a fitted model
...: arguments passed to other methods.
transform: logical; transform to the natural scale of the parameter

Examples

load_mgcv()
df <- data_sim("eg1", dist = "poisson", seed = 42, scale = 1 / 5)
m <- gam(y ~ s(x0) + s(x1) + s(x2) + s(x3),
  data = df, method = "REML",
  family = nb()
)
p <- theta(m)
