In this section, we demonstrate an application of the models detailed in Sect. 3. The
dataset includes 205 patients observed after operation for removal of malignant melanoma
in the period 1962–1977. The patients were followed until 1977. These data are
available in the timereg package in R (Scheike 2009). The observed time (T ) ranges
from 10 to 5565 days (from 0.0274 to 15.25 years, with mean = 5.9 and standard
deviation = 3.1 years) and refers to the time until the patient’s death or the censoring
time. Patients dead from other causes, as well as patients still alive at the end of the
study are censored observations (72%). We take ulceration status (absent, n = 115;
present, n = 90) and tumor thickness (in mm, mean = 2.92 and standard deviation =
2.96) as covariates. Remembering the identifiability issue in Sect. 4, in the destructive
exponentially weighted Poisson and the negative binomial models the probability p is
linked only to tumor thickness, whereas the parameter η is linked only to ulceration
