Plot residuals over time — ou_plot_fit

Visualize the residuals (differences between observed and fitted values) over time to assess model fit. Ideally, residuals should show no systematic patterns and be randomly scattered around zero.

Usage

ou_plot_fit_residuals(
  fit,
  palette = "Dark 3",
  main = "Residuals over Time",
  xlab = "Time",
  ylab = "Residual",
  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_residuals(fitted)
