dc.description.abstractThis paper investigates the effects of temporal aggregation when the aggregationfrequency is variable and possibly stochastic. The results that we report include, asa particular case, the well-known results on fixed-interval aggregation, such as whenmonthly data is aggregated into quarters. A variable aggregation frequency impliesthat the aggregated process will exhibit time-varying parameters and non-sphericaldisturbances, even when these characteristics are absent from the original model.Consequently, we develop methods for specification and estimation of the aggregatemodels and show with an example how these methods perform in practice.en_US
