9. In Example 11.8 apply the augmented data method with λi constant over periods and assess fit as compared to using the subject- and time-specific scale parameters λi t . Also consider both models when the gamma parameter ν is unknown, i.e. λi t ∼ Ga(0.5ν, 0.5ν)

and λi ∼ Ga(0.5ν, 0.5ν). Does this option favour a probit or logit link?
