The lung function data

Description

3164 male observations of lung function data previously analysed by Stanojevic et al. 2008 and Hossain et al. 2016.

Usage

data("lungFunction")

Format

A data frame with 3164 observations on the following 3 variables.

slf: the spirometric lung function, FEV_1 / FVC, which is an established index for diagnosing airway obstruction (males only)
height: the height in centimetres
age: the age

Details

The response variable is slf=FEV_1/FVC and the explanatory variable is height. The response variable slf is a ratio of forced expiratory volume in 1 second, FEV_1, to forced vital capacity, FVC. Spirometric lung function slf is an established index for diagnosing airway obstruction, e.g. Quanjer et al. 2010. The purpose here is to create centile curves of slf against height. More details about the analysis using GAMLSS of the FEV_1/FVC data can be found in Hossain et al. 2016.
