Both table variables can be considered ordinal. The variable visit
refers to visiting patterns recorded hospital. The category labels are
abbreviations of those given by Goodman (1983); e.g., "Regular" is
short for “received visitors regularly or patient went home”. The
variable stay refers to length of stay in hospital, in year groups.
