# 5-dimensional dataset with unit Frechet margins.

### Description

The dataset contains *590* (transformed) daily maxima of five
air pollutants recorded in Leeds (U.K.) during five winter seasons (November-Februrary)
between 1994 and 1998. Contains `NA`

's. Marginal transformation to unit Frechet was perfomed
by Cooley et al. (2010). Outliers have been removed according to Heffernan and Tawn (2004).

### Format

A *590*5* matrix.

### Details

The transformation to unit Frechet margins of the raw data has been considered by
Cooley et al (2010). Only the *100* data points with the largest radial components
were kept.
