LocomotorPerfor: Data on locomotor performance in small and large terrestrial...

In QBAsyDist: Asymmetric Distributions and Quantile Estimation

Description

A detailed description of these data is available in Iriarte-Diaz (2002). This dataset is also used in Gijbels et al. (2019c). For n = 142 species of mammals measurements on their body length, body mass (in kg) and maximum relative running speed were recorded. The maximum relative running speed measurement takes into account the body length of the mammals, and was obtained by dividing the maximum speed of the mammal species by its body length.

Usage

LocomotorPerfor

Format

A data frame with 142 rows and 2 variables:

Body_Mass

The body mass of n = 142 species of mammals.

MRRS

The maximum relative running speed measurement takes into account the body length of the mammals, and was obtained by dividing the maximum speed of the mammal species by its body length.
