a fitted model

...

arguments passed to other methods.

transform

logical; transform to the natural scale of the parameter

Value

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)
