this code is used to determine the parameters of johnson distribution for its bounded distribution .

说明：  基于贝叶斯网络的可靠性评估，输入个元件的故障率数据，计算各元件的条件概率，建立贝叶斯网络，贝叶斯推理，得到系统可靠工作情况下各元件的工作概率。(Based on the reliability evaluation of Bayesian network, input the failure rate data of components, calculate the conditional probability of each component, establish Bayesian network, Bayesian reasoning, and obtain the working probability of each component under the condition of reliable operation of the system)

matlab可用的HMM工具箱，包括DHMM，GHMM和混合HMM等(HMM toolbox matlab available, including DHMM, GHMM and hybrid HMM, etc.)

本算法程序基于实测汽轮机振动信号进行了测试及性能分析。理论分析及仿真结果表明，AR模型谱估计算法在阶次合适的情况下，能够取得较好的方差及分辨力性能，适合于振动信号的功率谱估计，且AIC准则为确定合理的模型阶次提供了有效依据。(This algorithm based on the measured turbine vibration signal testing and performance analysis. Theoretical analysis and simulation results show that, AR model spectrum estimation algorithm in appropriate circumstances the order, the variance can achieve better performance and resolution, suitable for vibration signal power spectrum estimation, and the AIC criterion to determine a reasonable model order provides an effective basis.)
