This is my Python attempt at a Yale Econometrics assignment that is expected to be done in R. The dataset comes from an R package, AER, which was created for the Econometrics course, and is full of datasets for the homeworks.
The data comes from Ray C. Fair's 1978 "A Theory of Extramarital Affairs" in the Journal of Political Economy. It data comes from self reported surveys in Redbook and Psychology Today, asking participents to provide information regarding their relationship happiness, years married, presence of children, and other factors. Fair was testing his own model about the allocation of an individual's time spent between a spouse and other activites. The surveys supported his model, but he needed more evidence. In reading Fair's paper, I think the dataset in AER doesn't have all of the attributes that Fair is working with when testing his own model.
My model asks how likely someone is to have an affair with the given data. Fair's model asks about the link between time spent with a spouse and having an affair.
