Available in PDF, EPUB and Kindle. Book excerpt: We suggest a convenient version of the omnibus test for normality, using skewness and kurtosis based on Shenton and Bowman [Journal of the American Statistical Association (1977) Vol. 72, pp. 206211], which controls well for size, for samples as low as 10 observations. A multivariate version is introduced. Size and power are investigated in comparison with four other tests for multivariate normality. The first power experiments consider the whole skewness-kurtosis plane; the second use a bivariate distribution which has normal marginals. It is concluded that the proposed test has the best size and power properties of the tests considered.

Book excerpt: There are a number of methods in the statistical literature for testing whether observed data came from a multivariate normal(MVN) distribution with an unknown mean vector and covariance matrix. Let X1 ... be an iid sample of size n from a p-variate normal distribution. Denote the sample mean and sample variance-covariance matrix by X and S respectively. Most of the tests of multivariate normality are based on the results that Yi-S-1/2(Xi - X), i=1,.., n, are asymptotically iid as p-variate normal than zero mean vector and identity covariance matrix. Tests developed by Andrews et al., Mardina and others are direct functions of Yi. We note that the N=np components of the Yi's put together can be considered as an asymptotically iid sample of size N from a univariate normal any well known test based on N independent observations for univariate normality. In Particular we can use univariate skewness and kurtosis tests, which are sensitive to deviations from normality.

Download or read book Exploring the Mechanics of Chronic Inflation and Hyperinflation written by Fernando de Holanda Barbosa and published by Springer. This book was released on 2016-10-17 with total page 121 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a theoretical framework to explain chronic inflation and hyperinflation. The roots of these two phenomenon are a fiscal monetary regime in which money issues finance the public deficit. Chronic inflation is modeled by using both the old and the new Keynesian model, with a different policy rule. Instead of using the Taylor rule, the central bank policy rule states that money is issued to finance the public deficit. The chronic inflation models take into account the fact that indexation mechanisms adjust prices and wages, yielding the inertial component of inflation. The dynamics of these models can be very unstable under parameter changes or shocks that hit the economy. The previous hyperinflation models surveyed in this book attempt to explain hyperinflation as a bubble phenomenon because they assume a constant real deficit financed by money. The mechanics of hyperinflation models in this book explains hyperinflation by a fiscal crisis, characterized by an increasing fiscal deficit. This fiscal crisis yields an intertemporal budget constraint that is not sustainable. The analysis of the pathology of hyperinflation uses the same tools employed to understand the pathologies of public debt and external debt crises. The hyperinflation model allows a taxonomy of hyperinflations, namely bubble, weak and strong, that can be tested with the inflation tax revenue curve.
