Channing House Data

Description:

     The 'channing' data frame has 462 rows and 5 columns.

     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 centre.  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 collected.  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.
