Simulation
Parametric Distributions
- Explain why the plug-in estimator for a property of a parametric distribution is so-named.
- Given a parametric distribution, estimates for its parameters, and a function for how the parameters are related to a particular property of the distribution, compute a plug-in estimate for that property.
The Parametric Bootstrap
- Explain the two “levels” of the parametric bootstrap in terms of what has actually happened in the real world and what is being simulated in bootstrap world.
- State the “recipe” for generating bootstrap estimates from a parametric distribution.
- Given a parametric distribution and estimators for its parameters, use the parametric bootstrap to obtain bootstrap estimates of a property of that distribution.
The Nonparametric Bootstrap
- Compare and contrast the parametric and nonparametric bootstraps.
- Explain the two “levels” of the nonparametric bootstrap in terms of what has actually happened in the real world and what is being simulated in bootstrap world.
- State the “recipe” for generating bootstrap estimates using the nonparametric bootstrap.
- Explain how to sample from the ECDF of a sample using
sample()
.
- Given an estimator for a property of a distribution, use the nonparametric bootstrap to obtain bootstrap estimates of that property of the distribution.
- Explain under what scenarios a parametric or nonparametric bootstrap is more appropriate.
The Bootstrap Percentile Confidence Interval
- Construct a coverage \(1 - \alpha\) bootstrap percentile confidence interval for a property of a distribution using either parametric or nonparametric bootstrap estimates of that property.
