The researchers whose trusted networks rank it highest, strongest advocate first. Every researcher gets a different order.

Fully modified narrow‐band least squares estimation of weak fractional cointegration (2011, unknown): “In our model, either choice will lead to identical first order asymptotic results, see Robinson (2005).”
Exact local Whittle estimation of fractionally cointegrated systems (2012, methodology): “Assumption 6 is used in Robinson (2005).”
Semiparametric inference in multivariate fractionally cointegrated systems (2010, unknown): “In order to allow for nonstationarity , tapering can be employed, as proposed by Velasco (1999a,b)—he assumed Type I non-stationarity, but according to Robinson (2005) this does not affect convergence rates, at least.”
Asymptotic theory of least squares estimators for nearly unstable processes under strong dependence (2007, methodology): “It should be pointed out that there exist other methods for dealing with long memory models, notably the Whittle estimates, the tapered Whittle estimates and related semiparametric procedures that were discussed in Velasco and Robinson [29] and Robinson [24].”
Determining the cointegrating rank in nonstationary fractional systems by the exact local Whittle approach (2007, methodology): “There are two main characterizations of fractional integration that have been employed in the literature, see e.g. Marinucci and Robinson (1999) and Robinson (2005).”
