An investigator is attempting to determine the health effects on families of living in crowded urban apartments. Several characteristics of the apartment have been measured, including square feet of living area per person, cleanliness, and age of the apartment. Several illness characteristics for the families have also been measured, such as number of infectious diseases and number of bed days per month for each child, and overall health rating for the mother. Suggest an analysis to use with these data.
