WebMay 2, 2015 · Bound testing as an extension of ARDL modelling uses F and t- statistics to test the significance of the lagged levels of the variables in a univariate equilibrium correction system when it is unclear if the data generating process underlying a time series is trend or first difference stationary. Webnot including the lagged dependent variable.7 The bounds F-test is a test that the k parameters on the regressors appearing in levels (plus the coefficient on the lagged de-pendent variable, q0) are jointly equal to zero: H0 = q0 +q1 +:::+qk = 0. This option is required, since critical values associated with the test differ based on the number ... Webtest-statistic Q MH can be bounded by two known distributions. As noted already, if e γ= 1 the bounds are equal to the ‘base’ scenario of no hidden bias. With increasing e , the bounds move apart reflecting uncertainty about the test-statistics in the presence of unobserved selection bias. Two scenarios are especially useful.
