Hierons, "Extending test sequence overlap by
invertibility," The Computer Journal, vol.
Note that in the above proof, the
invertibility assumption on I - [mu](A - B[N.sub.[dagger]]K) is only needed to prove the implication (I) [??] (II).
Due to the linearity and
invertibility ([DELTA][J[([[PHI].sub.3]).sup.aux]] = 1) of the matrix (21), system (17) has the solution given in (22).
In this subsection we will see how the study of the factorability of scalar and matrix functions is related to the
invertibility of certain classes of singular integral operators and, consequently, to the study of its spectra.
Tong, "A note on the
invertibility of nonlinear ARMA models", Journal of Statistical Planning and Inference, vol.
As a consequence of the proposition 2.12, we deduce the
invertibility of the operator M o [[partial derivative].sup.-S.sub.z].
Pshenitsyna [7] considered
invertibility preservers.
Coefficients of the ARMA models are also checked for both stationarity and
invertibility. (3) Furthermore, the residuals of the series are examined to make sure that they are white noise (Harvey, 1981; Enders; Greene, 2003).
Okoudjou,
Invertibility of the Gabor frame operator on the Wiener amalgam space, J.
Diagnostic checks on the AI[C.sub.c]-selected model involved the following steps: 1) verification of the resemblance of residuals to white noise (ACF plots, Ljung-Box test, cumulative periodogram test); 2) tests on the normality of residuals (Jarque-Bera and Shapiro-Wilks tests); and 3) confirmation of model stationarity,
invertibility, and parameter redundancy (Shapiro et al., 1968; Ljung and Box, 1978; Jarque and Bera, 1987; Box et al., 2008).

invertibility. The null hypothesis is cointegration between the variables In Table 3, FM-OLS estimations are summarized.
The problem that arises is related to the
invertibility problems discussed by Fernandez-Villaverde et al.
