In the article“Validation of a melanoma prognostic model” published in the Archives of Dermatology (Margolis et al., 1998), the authors reported a logistic regression model for the 5-year probability of death for melanoma patients. The variables in the model are age coded as 1 if greater than 60 and 0 otherwise, sex coded as 1 for male and 0 for female, tumor thickness entered as three dummy variables for the thickness intervals 0.76–1.69, 1.70–3.60, and >3.60, and a dummy variable for the location of the lesion coded as 1 for a truncal lesion and 0 otherwise.

The model was fit using the data from ???? = 1261 melanoma patients. Use the summary of the fitted logistic regression model given in Table 13.19 to answer the following questions.

(a) Estimate the 5-year probability of death for a 50-year-old male with a truncal lesion of tumor depth 2 mm.

(b) Estimate the 5-year probability of survival for a 50-year-old male with a truncal lesion of tumor depth 2 mm.

(c) Estimate the 5-year probability of death for a 50-year-old female with a truncal lesion of tumor depth 2 mm.

(d) Estimate the 5-year probability of survival for a 50-year-old female with a truncal lesion of tumor depth 2 mm.
