Quantile-quantile plot of sdmTMB randomized quantile residuals

Source: R/plot.R
plot_residual_qq.Rd

Computes randomized quantile residuals for each family component of a fitted sdmTMB model and draws a Q-Q plot. Delta models are faceted by component.

Usage

plot_residual_qq(fit, type = "mle-mvn", base_size = 11)

Arguments

fit

A fitted sdmTMB::sdmTMB() model.

type

Character. Residual type passed to stats::residuals() (falls back to "mle-eb" if the requested type fails). Default "mle-mvn".

base_size

Numeric. Base font size. Default 11.

Value

A ggplot object.

Examples

# \donttest{
mesh <- sdmTMB::make_mesh(sdmTMB::pcod, c("X", "Y"), cutoff = 20)
m1 <- sdmTMB::sdmTMB(
  density ~ 0 + as.factor(year),
  data = sdmTMB::pcod,
  time = "year",
  mesh = mesh,
  family = sdmTMB::delta_lognormal()
)
# Automatically plots all components of the delta model
plot_residual_qq(m1)
