Method for generating parametric bootstrap estimates from a fitted model.
bootstrap(object, B = 1000, extra_param = FALSE, ...)an object representing a fitted model (see 'Details').
an integer for number of bootstrap replicates (default
1,000).
if TRUE, bootstrap is also performed for extra parameters
(see 'Details').
additional optional arguments to pass to ibControl.
A matrix p (size of parameter) times B of bootstrapped estimates.
This method is a simple wrapper around the ib method
where number of iterations is set to 1.
