中文说明：包括回归分析和概率统计，这个有中文注释，看得明白，鲁棒性好，性能优越，分析了该信号的时域、频域、倒谱，循环谱等,是机器学习的例程，可以得到很精确的幅值、频率、相位估计。
English Description：
Including regression analysis and probability and statistics, the Chinese notes, to understand it, good robustness, superior performance, analyzes the the signal in time domain and frequency domain, cepstrum, cyclic spectrum, machine learning routines can be very accurate amplitude, frequency and phase estimation is obtained.
