       cost: The capital cost of construction in millions of
             dollars adjusted to 1976 base.

       date: The date on which the construction permit was
             issued.  The data are measured in years since Jan-
             uary 1 1990 to the nearest month.

         t1: The time between application for and issue of the
             construction permit.

         t2: The time between issue of operating license and
             construction permit.

        cap: The net capacity of the power plant (MWe).

         pr: A binary variable where `1' indicates the prior
             existence of a LWR plant at the same site.

         ne: A binary variable where `1' indicates that the
             plant was constructed in the north-east region of
             the U.S.A.

         ct: A binary variable where `1' indicates the use of a
             cooling tower in the plant.

         bw: A binary variable where `1' indicates that the
             nuclear steam supply system was manufactured by
             Babcock-Wilcox.

      cum.n: The cumulative number of power plants constructed
             by each architect-engineer.

         pt: A binary variable where `1' indicates those plants
             with partial turnkey guarantees.

        The `nuclear' data frame has 32 rows and 11 columns.

        The data relate to the construction of 32 light water
        reactor (LWR) plants constructed in the U.S.A in the
        late 1960's and early 1970's.  The data was collected
        with the aim of predicting the cost of construction of
        further LWR plants.  6 of the power plants had partial
        turnkey guarantees and it is possible that, for these
        plants, some manufacturers' subsidies may be hidden in
        the quoted capital costs.
