WebNov 24, 2012 · Abstract. This paper presents an analysis of asset allocation strategies when the asset returns are governed by a discrete-time higher-order hidden Markov model (HOHMM), also called the weak hidden Markov model. We assume the drifts and volatilities of the asset returns switch over time according to the state of the HOHMM, in which the ... WebMar 29, 2024 · In general, the transition matrix representing the kth order Markov chain should not contain the rows of invalid k-tuples (tuples representing a sequence of states corresponding to an impossible path). As for the (C1, END1) row, it's not an all zero row because when you're at END1 your next state is END1 with a probability of 1.
