_A_r_g_u_m_e_n_t_s_:

    volt: The voltage (in kV).

    time: The failure or censoring time in hours.

    cens: The censoring indicator; `1' means right-censored
          data.

_S_U_M_M_A_R_Y_:

     The `hirose' data frame has 44 rows and 3 columns.

     PET film is used in electrical insulation.  In this
     accelerated life test the failure times for 44 samples
     in gas insulated transformers.  4 different voltage
     levels were used.

_D_A_T_A _D_E_S_C_R_I_P_T_I_O_N_:

     This data frame contains the following columns:

_S_O_U_R_C_E_:

     The data were obtained from

     Hirose, H. (1993) Estimation of threshold stress in
     accelerated life-testing.  IEEE Transactions on Relia-
     bility, 42, 650-657.
