MRS3IR_SIM: MATLAB function to simulate trajectories of a Markov regime-switching (MRS) model with 3 independent regimes


  • Joanna Janczura
  • Rafal Weron


MRS3IR_SIM(P,PARAM,MODEL,STARTVALUE,KSI_0,T,N) generates N trajectories of a Markov regime-switching (MRS) model with 3 independent regimes: (i) an AR(1) process in the base regime, X(t+1)=phi_1*X(t)+c_1+sigma_1*|X(t)|^g_1*N(0,1), (ii) a Gaussian (MODEL='G'), lognormal ('LN'), Pareto ('P'), Weibull ('W') or exponential ('E') distributed spike regime, (iii) and a shifted 'inverse lognormal' drop regime. P, PARAM and KSI_0 are the transition matrix, model parameters and probabilities classifying the first observation to one of the regimes, respectively, returned by MRS3IR_EST. STARTVALUE is the starting point for the simulated trajectories and T is the length of the trajectories.
