The introduction of permutation tests by R. A. Fisher relaxed the paramet ric structure requirement of a test statistic. For example, the structure of the test statistic is no longer required if the assumption of normality is removed. The between-object distance function of classical test statis tics based on the assumption of normality is squared Euclidean distance. Because squared Euclidean distance is not a metric (i. e. , the triangle in equality is not satisfied), it is not at all surprising that classical tests are severely affected by an extreme measurement of a single object. A major purpose of this book is to take advantage of the relaxation of the struc ture of a statistic allowed by permutation tests. While a variety of distance functions are valid for permutation tests, a natural choice possessing many desirable properties is ordinary (i. e. , non-squared) Euclidean distance. Sim ulation studies show that permutation tests based on ordinary Euclidean distance are exceedingly robust in detecting location shifts of heavy-tailed distributions. These tests depend on a metric distance function and are reasonably powerful for a broad spectrum of univariate and multivariate distributions. Least sum of absolute deviations (LAD) regression linked with a per mutation test based on ordinary Euclidean distance yields a linear model analysis which controls for type I error.
A seminal figure in American literature and philosophy, Ralph Waldo Emerson is considered the apostle of self-reliance, fully alive within his ideas and disarmingly confident about his innermost thoughts. Yet the circumstances around "The American Scholar" oration--his first great public address and the most celebrated talk in American academic history--suggest a different Emerson. In Understanding Emerson, Kenneth Sacks draws on a wealth of contemporary correspondence and diaries, much of it previously unexamined, to reveal a young intellectual struggling to define himself and his principles. Caught up in the fierce dispute between his Transcendentalist colleagues and Harvard, the secular bastion of Boston Unitarianism and the very institution he was invited to honor with the annual Phi Beta Kappa address, Emerson agonized over compromising his sense of self-reliance while simultaneously desiring to meet the expectations of his friends. Putting aside self-doubts and a resistance to controversy, in the end he produced an oration of extraordinary power and authentic vision that propelled him to greater awareness of social justice, set the standard for the role of the intellectual in America, and continues to point the way toward educational reform. In placing this singular event within its social and philosophical context, Sacks opens a window into America's nineteenth-century intellectual landscape as well as documenting the evolution of Emerson's idealism. Engagingly written, this book, which includes the complete text of "The American Scholar," allows us to appreciate fully Emerson's brilliant rebuke of the academy and his insistence that the most important truths derive not from books and observation but from intuition within each of us. Rising defiantly before friend and foe, Emerson triumphed over his hesitations, redirecting American thought and pedagogy and creating a personal tale of quiet heroism.
