Abstract: A novel methodology is presented that allows us to estimate both the long memory parameter of a (possibly nonstationary) time series and the frequency which maximizes the spectral density. We derive limiting distributions, assess them through a simulation exercise and also provide a valid bootstrap scheme that uses both time domain and frequency domain information. We then illustrate the usefulness of our model in capturing the salient features of dynamics of different datasets.
