Phase spectrum with MEM

Hi everyone, I need to calculate power spectrum and phase spectrum with Maximum entropy method, For power spectrum I used pburg command but I do not know about phase spectrum calculation. Is there any way to calculate phase spectrum from MEM ?

Like when we perform FFT, we get real and imaginary components; And we can calculate amplitude and phase spectrum by simple relations between real and imaginary parts or simply using the abs command for amplitude and angle for phase. Similarly, can we calculate separate amplitude and phase spectrum from MEM ?
