36 Moreover 3 because we now have independent and identically distributed observations, we can use results from classlcal statistics to estimate E{YI}/E[~ I] . 3. 2 Regenerative Processes in ContinuousTime A regenerative process { ~ (t)3 t ~ 0) in K dimensions is a stochastic process which starts afresh probabilistically at an increasing sequence 0 ~R I < R2 . . of random epochs on the time axis Thus; between any two consecutive regeneration epochs the portion [ X (t)3 Rj ~ t < Rj + 1 ] R. 3 and [ 0 3 ~) .
