dataset gives data on a sample of patients
suffering from melanoma (skin cancer) cross-classified by the type of cancer and
the location on the body. Determine whether the type and location are
independent. Examine the residuals to determine whether any dependence can be
ascribed to particular type/location combinations.
on social mobility of men in the UK was assembled by Blane et al.
(1999) in JRSS-A. A sample of men aged 45-64 was drawn from the 1971 census and
1981 census and the social class of the man was recorded at each timepoint. The
classes are I=professional, II=semi-professional, IIIN=skilled non-manual, IIIM=skilled
manual, IV=semi-skilled, V=unskilled. Check for
symmetry, quasi-symmetry, marginal homgeneity and quasi-independence.
The dataset contains data on murder cases in Florida in 1977. The data is cross-classified by the race (black or white) of the victim, of the defendant and whether the death penalty was given. Determine the most appropriate dependence model between the variables.
