Test uniformity of PIT residuals

Source: R/diagnostics_sim.R
test_uniformity.Rd

If the model is correct, PIT residuals should follow Uniform(0, 1). Applies a Kolmogorov-Smirnov test against that null. Equivalent to DHARMa::testUniformity().

Usage

test_uniformity(
  object,
  observed = NULL,
  nsim = 250L,
  seed = 123L,
  plot = FALSE
)

Arguments

object

A fitted model, a numeric vector of PIT residuals, or a matrix of simulations

observed

Observed data (if object is simulations matrix)

nsim

Number of simulations (default 250)

seed

Random seed (default 123)

plot

If TRUE, draws a QQ plot

Value

An htest object (KS test result)
