MODELLING TIME SERIES OF COUNTS: AN INAR APPROACH 119
of Bernoulli trials [11]. Here we focused on the INAR(1) models which are a class of observation-driven models particularly suited for stock type data. We illustrated the modelling of a time series with INAR(1) models.
Several generalizations of the INAR(1) models are available in the literature, namely: INAR(p) models [23, 9], models with moving average components, INARMA, [33], periodic models [35] and bivariate models [37].
