Abstract
In Section 10.3 we obtained a central limit theorem for data-based estimators \(\widehat{\varvec{\nu }}^*_n(H)\) of cluster functionals \({\varvec{\nu }}^*(H)\). Theorem 10.3.1 allows us to construct confidence intervals for \({\varvec{\nu }}^*(H)\) of the form \( \left( \widehat{\varvec{\nu }}^*_{n,{r_{n}}}(H)-\frac{1}{\sqrt{k}}\sigma (H)z_{\beta /2},\widehat{\varvec{\nu }}^*_{n,{r_{n}}}(H) +\frac{1}{\sqrt{k}}\sigma (H)z_{\beta /2}\right) \;,\) where \(\sigma ^2(H)\) is the limiting variance of the estimator and \(z_{\beta /2}\) is \(1-\beta /2\) quantile of the standard normal random variable. Unfortunately, in most cases, the limiting variance depends on unknown parameters and has a complicated form, often an infinite series, as can be seen in the examples of Section 10.4.

12.3 Bibliographical notes
This chapter is essentially an adaptation and extension of [Dre15] and [DDSW18]. The multiplier bootstrap for tail array sums was also considered in [JK19].
The main technical tools come from [Kos03, Kos08] to which we refer for the general theory of various bootstrap methods for i.i.d. sequences. Other bootstrap procedures for tail array sums are considered in [DMC12] and [MZ15].
For Markov chains with a regeneration structure, bootstrap techniques for extremal statistics were developed in [BCT13].
