QQ plot of residuals — ou_plot_fit

Visualize a normal Q-Q plot of the residuals to assess their distributional properties. Ideally, residuals should lie approximately along the reference line, indicating normality.

Usage

ou_plot_fit_qq(
  fit,
  palette = "Dark 3",
  main = "Normal Q-Q Plot of Residuals",
  xlab = "Theoretical Quantiles",
  ylab = "Sample Quantiles",
  alpha = 0.8,
  ...
)

Arguments

fit: A fit_affectOU object
palette: Color palette. Should be one of grDevices::hcl.pals().
main: Main title
xlab: X-axis label
ylab: Y-axis label
alpha: Alpha transparency for colors (0 = transparent, 1 = opaque)
...: Additional graphical parameters

Value

NULL (invisibly), called for side effects only.

Examples

model <- affectOU(theta = 0.5, mu = 0, gamma = 1)
sim <- simulate(model, stop = 500, dt = 0.01, save_at = 0.1)
data <- as.data.frame(sim)
fitted <- fit(model, data = data$value, times = data$time)
ou_plot_fit_qq(fitted)
