is considered. The
are the occurrence times of a random event generated by a Poisson stochastic point process. Each
is the amplitude associated with the
th event at random time
and is constructed from
and the interarrival time
, according to the first-order autoregressive exponential time series model (EAR(l)). Moments and joint distributions for the bivariate process are obtained, as well as the distribution of some extreme values related to the bivariate process.
