          leaving the centre or July 1, 1975 whichever event

    time: The length of time (in months) that the resident
          spent at Channing House.  (`time=exit-entry')

    cens: The indicator of right censoring.  1 indicates
          that the resident died at Channing House, 0 indi-
          cates that they left the house prior to July 1,

     Channing House is a retirement centre in Palo Alto,
     California.  These data were collected between the
     opening of the house in 1964 until July 1, 1975.  In
     that time 97 men and 365 women passed through the cen-
     tre.  For each of these, their age on entry and also on
     leaving or death was recorded.  A large number of the
     observations were censored mainly due to the resident
     being alive on July 1, 1975 when the data was col-
     lected.  Over the time of the study 130 women and 46
     men died at Channing House.  Differences between the
     survival of the sexes, taking age into account, was one
     of the primary concerns of this study.
