摘要
We consider a general class of time series linear models where parameters switch according to a known fixed calendar. These parameters are estimated by means of quasi-generalized least squares estimators. Conditions for strong consistency and asymptotic normality are given. Applications to cyclical ARMA models with non constant periods are considered.
