多元数据分析的主分量分析投影，利用贝叶斯原理估计混合logit模型的参数，分析了该信号的时域、频域、倒谱，循环谱等,IMC-PID是利用内模控制原理来对PID参数进行计算，GSM中GMSK调制信号的产生，外文资料里面的源代码，采用偏最小二乘法。- Principal component analysis of multivariate data analysis projection, Bayesian parameter estimation principle mixed logit model, Analysis of the signal time domain, frequency domain, cepstrum, cyclic spectrum, etc. The IMC- PID is using the internal model control principle for PID parameters is calculated, GSM is GMSK modulation signal generation, Foreign materials inside the source code, Partial least squares method.
