catdata (version 1.2.4)

vaso: Vasoconstriciton and Breathing

Description

The vaso data contains binary data. Three test persons inhaled a certain amount of air with different rates. In some cases a vasoconstriction (neural constriction of vasculature) occured at their skin. The goal of the study was to indicate a correlation between breathing and vasoconstriction. The test persons repeated the test 9, 8, 22 times. So the dataframe has 39 observations.

Usage

Format

A data frame with 39 observations on the following 3 variables.

vol

amount of air

rate

rate of breathing

vaso
