how to get amplitude and phase from pyulear?

Hi all, I have a time series data. I isolated the oscillation signals with Singular spectrum analysis and trying to predict the oscillation of the principle components with Autoregressive method. I run the pyulear to have the frequency of the o oscillation but I do not know how to have the amplitude and phase. Is here any way directly have the amplitude and phase information from the pyulear result?

Thanks in advance. Zhongkui
