beatenberg: Beatenberg Forest Temperature Data (In Unit Fréchet Scale)

Description

Preprocessed pairs of temperatures in unit Fréchet scale from Beatenberg forest, registered under forest cover and in the open field.

Usage

beatenberg

Format

The beatenberg data frame has 2839 rows and 2 columns: x (forest cover) and y (open field).

Details

Preprocessing was conducted as described in Ferrez et al (2011), and for applications of this dataset within the context of extreme value theory see de Carvalho et al. (2013), de Carvalho and Davison (2014) as well as Castro and de Carvalho (2017).
