The data set provides the odds ratios and correlations as measures of
associations of the binary outcome impaired pulmonary function for a family of
four with two parents and two siblings.
These correlations and odds ratios are obtained from Qaqish et al. (2012) based
on a regression analysis of a common data set of parents and siblings with
chronic obstructive pulmonary disease and their controls.
