We consider the problem of testing for the existence of fixed effects and random effects in one-way models, where the groups are correlated and the disturbances are dependent. The classical F-statistic in the analysis of variance is not asymptotically distribution-free in this setting. To overcome this problem, we propose a new test statistic for this problem without any distributional assumptions, so that the test statistic is asymptotically distribution-free. The proposed test statistic takes the form of a natural extension of the classical F-statistic in the sense of distribution-freeness. The new tests are shown to be asymptotically size α and consistent. The nontrivial power under local alternatives is also elucidated. The theoretical results are justified by numerical simulations for the model with disturbances from linear time series with innovations of symmetric random variables, heavy-tailed variables, and skewed variables, and furthermore from GARCH models. The proposed test is applied to log-returns for stock prices and uncovers random effects in sectors. [ABSTRACT FROM AUTHOR]

The "Part of the Solution" article describes how the food industry has evolved its strategies to respond to critics and government regulation by co-option and appeasement to create a less hostile environment. Rather than focusing research on single industries it would be more efficient and productive to focus on corporate political activities (CPAs) that directly influence democratic institutions and processes having authority over laws, policy, rules and regulations that govern industry. The most influential and direct CPA are election campaign donations, lobbying, and the reverse revolving door. In the United States those CPA flow from rights of corporations that underlie all industry strategies. The US history of how corporations obtained their rights is described, and research about the affirmative effects of those three CPA is summarized. Health research is needed about those CPA and their effects on health law, policy and regulation in the United States and other nations. [ABSTRACT FROM AUTHOR]
