_U_s_a_g_e_:

     bp(y, id, censor=1)

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

       y: Vector of times.

      id: Vector of corresponding individual identifiers for
          who had which sequence of times.

  censor: Vector of censoring indicators.

_V_a_l_u_e_:

     `bp' creates a vector of length `sum(y)' of cumulative
     numbers of previous events for each individual for use
     in fitting birth processes with `ehr'. Add one if the
     process starts at an event.

     `ehr', `ident', `pp', `tccov', `tpast', `ttime',
     `tvcov'.
