_D_e_s_c_r_i_p_t_i_o_n:

     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.

_F_o_r_m_a_t:

     This data frame contains the following columns:


     '_v_o_l_t' The voltage (in kV).

     '_t_i_m_e' The failure or censoring time in hours.

     '_c_e_n_s' The censoring indicator; '1' means right-censored data.

_S_o_u_r_c_e:

     The data were obtained from

     life-testing. _IEEE Transactions on Reliability_, *42*, 650-657.
