We analyze the connectedness between major cryptocurrencies and nonfungible tokens (NFTs) for diferent quantiles employing a time-varying parameter vector autoregression approach. We fnd that lower and upper quantile spillovers are higher than those at the median, meaning that connectedness...

A new method to estimate longevity risk based on the kernel estimation of the extreme quantiles of truncated age-at-death distributions is proposed. Its theoretical properties are presented and a simulation study is reported. The flexible yet accurate estimation of extreme quantiles of...

We propose a method to generate a warning system for the early detection of time clusters in discrete time series. Two approaches are developed, one using an approximation of the return period of an extreme event, independently of the nature of the data, the other using an estimation of the...
