Excuse what may be an obvious question about bootstrapping. I got sucked in the Bayesian world early and never really explored bootstrapping as much as I should have.
I ran across an analysis in which the authors were interested in a survival analysis related to some time to failure data. They had about 100 points and used regression to fit a Weibull distribution to the data. A result of this they obtained estimates of the scale and shape parameters. A very traditional approach. However, they next used bootstrapping to sample from the original data set and, for each new sample, performed a regression and came up with a new Weibull distribution. The results of the bootstrapping was then used to construct confidence intervals on the survival distribution.
My intuition is a bit conflicted. I'm familiar with bootstrapping confidence intervals on parameters, but not seen it used for constructing distribution confidence intervals.
Can anyone point me toward a reference/source that might provide some insight? Thanks in advance.
