摘要
对于连续时间和离散时间三状态隐马氏模型,给出了观测过程直到三维的似然函数流的显式表达.作为一个应用,证明了观测过程可逆性的充分必要条件.
For the continuous-time and the discrete-time three-state hidden Markov model, the flux of the likelihood function up to 3-dimensional of the observed process is shown explicitly. As an application, the sufficient and necessary condition of the reversibility of the observed process is shown.
