Webbcurrencies in both markets. It is thus difficult to generalize the comparison between the exchange rate pass-through effects even in the simplest case in which the demand slopes in each market are identical. Unit root testing The standard Augmented Dickey-Fuller (ADF) test is performed to assess the degree of integration of the variables. WebbDetails. Compared with the Augmented Dickey-Fuller test, Phillips-Perron test makes correction to the test statistics and is robust to the unspecified autocorrelation and heteroscedasticity in the errors. There are two types of test statistics, Z_ {\rho} Z ρ and Z_ {\tau} Z τ, which have the same asymptotic distributions as Augmented Dickey ...
