(15 for each spouse) and 17 events to be predicted out of 124 couples.
With so many predictors and so few events, you can easily get better
than 90% correct predictions by pure chance. Gottman has a whole
industry churning out research, books, TV interviews, magazine articles,
etc. that is all based on what is commonly known as "capitalizing on
chance" or "overfitting".
