Plots for ddhazard Object

Description

Plot of estimated state space variables from a ddhazard fit.

Usage

## S3 method for class 'ddhazard'
plot(
  x,
  xlab = "Time",
  ylab = "Hazard",
  type = "cov",
  plot_type = "l",
  cov_index,
  ylim,
  col = "black",
  add = FALSE,
  do_alter_mfcol = TRUE,
  level = 0.95,
  ddhazard_boot,
  ...
)

Arguments

x	result of ddhazard call.
xlab, ylab, ylim, col	arguments to override defaults set in the function.
type	type of plot. Currently, only "cov" is available for plot of the state space parameters.
plot_type	the type argument passed to plot.
cov_index	the index (indices) of the state space parameter(s) to plot.
add	FALSE if you want to make a new plot.
do_alter_mfcol	TRUE if the function should alter par(mfcol) in case that cov_index has more than one element.
level	level (fraction) for confidence bounds.
ddhazard_boot	object from a ddhazard_boot call which confidence bounds will be based on and where bootstrap samples will be printed with a transparent color.
...	arguments passed to plot.default or lines depending on the value of add.

Details

Creates a plot of state variables or adds state variables to a plot with indices cov_index. Pointwise 1.96 std. confidence intervals are provided with the smoothed co-variance matrices from the fit.

Value

Returns NULL using invisible.

Examples

library(dynamichazard)
fit <- ddhazard(
 Surv(time, status == 2) ~ log(bili), pbc, id = pbc$id, max_T = 3600,
 Q_0 = diag(1, 2), Q = diag(1e-4, 2), by = 50,
 control = ddhazard_control(method = "GMA"))
plot(fit)
plot(fit, cov_index = 2)
