Hou.Perron Modified semiparametric local Whittle estimator of Hou and Perron (2014). Estimates memory parameter robust to low frequency contaminations.

1	Hou.Perron(data, m)

`data`	data vector of length T.
`m`	bandwith parameter specifying the number of Fourier frequencies used for the estimation usually `floor(1+T^delta)`, where 0<delta<1.
