A study was recently published suggesting that the amount of weight a woman gains after her first pregnancy could be associated with stillbirth for subsequent pregnancies. If we wanted to predict the probability of stillbirth (yes/no) using the amount of weight gain as a continuous variable, what statistical analysis should we use?

a) Chi Square test

b) t-test comparison of means

c) None listed

d) Poisson Probability estimate

e) logistic regression
