Plots Related to the the 'Adapted Paik et Al.' Model

Usage

# S3 method for class 'AdPaik'
plot(
  x,
  which = c(1, 2),
  captions = c("Plot 1: Baseline Hazard", "Plot 2: Posterior Frailty Estimate"),
  ...
)

Arguments

x: An object of class 'AdPaik'.
which: A numeric vector indicating which plots to display. Choices: 1 = Baseline Hazard, 2 = Posterior Frailty Estimate.
captions: A character vector with captions for each plot.
...: Additional arguments to be passed to other methods.

Value

No return value. This function generates plots.
