_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 Reliability, 42, 650-657.
