Fit the logistic mean function y ∼ myopathy + log(ck) + my opathy: log(ck). Obtain a Type II Analysis of Deviance table and summarize the results. Draw and interpret an effects plot, assuming the interaction is significant.

Donner party (Data file: Donner) In the winter of 1846–1847, about 90 wagon train emigrants in the Donner party were unable to cross the Sierra Nevada Mountains of California before winter, and almost half of them starved to death. The data in file Donner from Johnson (1996) include some information about each of the members of the party. The variables include age, the age of the person; sex, whether male or female; status, whether the person was a member of a family group, a hired worker for one of the family groups, or a single individual who did not appear to be a hired worker or a member of any of the larger family groups; and y, a factor with levels died and survived.
