    Sammanfattning : We discuss the Normal inverse Gaussian (NIG) distribution in modeling volatility in the financial markets. Refining the work of Barndorff-Nielsen (1997) and Andersson (2001), we introduce a new parameterization of the NIG distribution to build the GARCH(p,q)-NIG model. LÄS MER

  3. 2. Testing for Unit Root against LISTAR Model : Wavelet Improvement under GARCH Distortion

    Detta är en avhandling från Växjö : Växjö university Press

    Författare :Yushu Li; Växjö universitet.; [2008]
    Nyckelord :;

    Sammanfattning : In this paper we propose a Nonlinear Dickey-Fuller F test for unit root against first order Logistic Smooth Transition Autoregressive LISTAR (1) model with time as the transition variable. The Nonlinear Dickey-Fuller F test statistics is established under the null hypothesis of random walk without drift and the alternative model is a nonlinear LSTAR (1) model. LÄS MER

We find that the financial crisis affects financially distressed firms more heavily than non-distressed firms. LÄS MER
