Q qij denotes the transition probability matrix for shifts between regimes where k. For an irreducible and aperiodic Markov chain qij = p t = sj t−1 = si i j = 1 with a finite state space, there is a unique vector of stationary probabilities denoted by = 1 k . In this specification the variance of t is assumed to be constant in every regime but can vary across regimes. 21) could be used to model the time series. Note that, in a more general setting, a higher order of AR for each regime could be allowed.

Non-negativity constraints on the a and t t t t i bj i = 0 q, j = 1 p make t the conditional standard deviation of the t process. If the distribution Zt is symmetric, the effect of a shock t−k k ≤ q on the present 1 2 volatility is proportional to the difference ak −ak , the sign of which can be either positive or negative. The non-negativity constraints on the parameters make the model linear, and stationarity can be analysed.
