This paper studies the model risk; the risk of selecting a model for estimating the Value-at-Risk (VaR). By considering four GARCH-type volatility processes exponentially weighted moving average (EWMA), generalized autoregressive conditional heteroskedasticity (GARCH), exponential GARCH...

In this paper we will use the Bayesian inference for the parameters that appear in the queueing systems. We will estimate these parameters and we will build confidence intervals and significance tests for them, considering the parameters of the exponential Poisson and geometric distribution. We...

In this article we will determine the confidence regions for the parameters of a distribution and versions of some tests without using tables that contain centiles.

In this paper we reinterpret the location quotient, the commonly employed measure of regional industrial agglomeration, as an estimator derived from Ellison and Glaeser’s (1997) dartboard framework. This approach provides a theoretical foundation on which to build statistical tests for the...

Los modelos econométricos, sirven como instrumento para la realización de estudios sobre sus parámetros estructurales, que están enfocados tanto a la interpretación de los valores que toman dichos parámetros, como a contrastar si se cumplen determinadas restricciones sobre los mismos. Sin...

Students are very interested in lecture examples and class exercises involving data connected to the maiden voyage and the sinking of the liner Titanic. Information on the passengers and their fate can be used to explore relationships between various tests for differences in survival rates...

This paper estimates the evolution of equilibrium real home prices in the United States and finds that despite recent declines, single-family homes remained 8 to 20 percent overvalued as of the first quarter of 2008. In the short run, the gap between actual and equilibrium prices does not exert...

Looking ahead to the creation of a Gulf Cooperation Council (GCC) Currency Union in 2010, the paper covers some implications for the statistical programs of the GCC countries. Despite uncertainty over the structure of the proposed union, the paper envisions several types of mutually reinforcing...
