We therefore studied whether topical application of zinc to TB skin test sites would augment test results in Lima, Peru, a TB-endemic area in which false-negative skin-test results are frequent (1 ).
Using data from the 2004 follow-on survey, the Durbin-Wu-Hausman test (augmented regression test) was performed to test for endogeneity between media exposure and the respective outcomes [ 16].
In brief, the number of differences is defined as d, which may be determined using either a Kwiatkowski Phillips Schmidt Shin (KPSS) test, augmented dickey fuller test, or the Phillips Perron test.
We also use the Johansen cointegration for the robustness of the results, because augmented Dickey Fuller test and Phillips Perron tests give contradictory results about the order or integration.
In this model, we first put the data set to ADF stationarity test (augmented DF stationarity test).
Delta y_{i,t} = alpha_{i} + delta_{i} t + theta_{t} + rho_{i} y_{i,t - 1} + varsigma_{i,t} quad {text{where}}quad {text{i}} = 1,2, ldots,Nquad t = 1,2, ldots,T (1)This test might be treated as a pooled Dickey Fuller or augmented Dickey Fuller test potentially with different time lags across the units of the panel.
The PP method estimates the non- augmented DF test equation, and it can be seen as a generalization of the ADF test procedure, which allows for fairly mild assumptions concerning the distribution of errors.
Rice crop data were analyzed using the ordinary least square method and the augmented Dickey Fuller test.
The stationary test (augmented Dickey Fuller [ADF] Test) is applied to the SZII time series to test whether a unit root test exists in the ARIMA model.
Various 'service load damage models' were proposed in the 1970s which at best successfully augmented extensive testing under simulated service load conditions.
