Unlike the finite-variance case, it emerges that the limiting distribution, after suitable normalization, is not always more concentrated around zero when residuals rather than true innovations are employed.enUniversitätsbibliothek Dortmund310Diagnostic checking in linear processes with infinite variancereport
