The problem is in the idea. How do you bootstrap a time series? Once
you have sampled a set of observations with replacement, how do you
then define the time order for such a sample, with typically some
observations repeated and some missing? There are ideas in the
literature on how to do it, but -bootstrap- does not implement them.
