In this paper we investigate the properties of the Lagrange Multiplier (LM) test for autoregressive conditional heteroskedasticity (ARCH) and generalized ARCH (GARCH) in the presence of additive outliners (AO's). We show analytically that both the asymptotic size and power are adversely...

The classical statistical model relates to n independent random variables having a common distribution. In this paper we consider the situation where the common distribution involves an unknown parameter, and where at time 0<t<1 only the first [nt] random variables are observed.

We study the generalized assignment problem, under a probabilistic model for its cost and requirement parameters. First … additional condition on the parameters, we show that the optimal value, normalized by dividing by the number of jobs, converges …

Many common statistical models can be specified as linear models with restrictions imposed on the parameters. A large … amount of these models impose restrictions which do not allow for the analytical construction of the probability density … function (pdf) of the parameters given the restrictions. This is often implicitly assumed which leads to an inconsistency as …

In this paper we analyze the sensitivity of unit root inference to nonlinear transformations through Bayesian techniques. We make joint inference about the Box-Cox transformation, which includes the cases yt and log(yt), and the unit root. When we apply our method to the fourteen Nelson-Plosser...
