TLDR
In this paper, 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. 206 and 211], was proposed.
Abstract
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. 206–211], 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.

Uncertainty, Financial Frictions, and Investment Dynamics

TL;DR: In this paper, the authors analyzed the economic significance of the traditional "wait-and-see" effect of uncertainty shocks and pointed to financial distortions as the main mechanism through which fluctuations in uncertainty affect macroeconomic outcomes.

Asymmetric causality tests with an application

TL;DR: In this article, the authors argue that there are several logical reasons for the existence of asymmetric causal effects that need to be taken into account but usually are neglected in the literature, and they suggest allowing for asymmetry in the causality testing by using the cumulative sums of positive and negative shocks.

Optimal Portfolio Allocation under Higher Moments

TL;DR: In this article, the authors evaluate how departure from normality may affect the allocation of assets and propose a Taylor series expansion of the expected utility, which allows to focus on certain moments and to compute the optimal portfolio allocation numerically.

Measures of multivariate skewness and kurtosis with applications

TL;DR: In this article, the authors developed measures of multivariate skewness and kurtosis by extending certain studies on robustness of the t statistic, and the asymptotic distributions of the measures for samples from a multivariate normal population are derived and a test for multivariate normality is proposed.

A test for normality of observations and regression residuals

TL;DR: In this paper, the Lagrange multiplier procedure or score test on the Pearson family of distributions was used to obtain tests for normality of observations and regression disturbances, and the tests suggested have optimum asymptotic power properties and good finite sample performance.

A Suggestion for Using Powerful and Informative Tests of Normality

TL;DR: For testing that an underlying population is normally distributed the skewness and kurtosis statistics, √b 1 and b 2, and the D'Agostino-Pearson K 2 statistic that combines these two statistics have been shown to be powerful and informative tests.
