Modelling the trend and seasonals within an AIDS model of the demand for alco...
The argument that is put forward in this paper is that failure to represent stochastic trend and stochastic seasonality in an AIDS model leads to a misspecified and possibly... -
Common cycles in seasonal non-stationary time series (replication data)
This paper extends the notion of common cycles to quarterly time series having unit roots both at the zero and seasonal frequencies. It is shown that common cycles are present... -
Bayesian inference for periodic regime-switching models (replication data)
We present a general class of nonlinear time-series Markov regime-switching models for seasonal data which may exhibit periodic features in the hidden Markov process as well as... -
Persistence of shocks on seasonal processes (replication data)
The paper addresses the issue of measuring the persistence of shocks on seasonally integrated processes observed at quarterly intervals. We show that the amplitude of the...
