The 11 neotropical species of Fannia belonging to the pusio sub-group (canicularis group), are keyed F. dodgei Seago; F. femoralis (Stein); F. pamplonae Couri & Araújo; F. parafemoralis Araújo & Couri; F. paraisensis Araújo & Couri; F. punctivervis Malloch; F. pusio (Wiedemann); F. sabroskyi Seago; F. snyderi Seago; F. trimaculata (Stein); F. trimaculatoides Couri & Pamplona. The key is address...

Choosing the performance criterion to be mean squared error matrix, we have compared the least squares and Stein-rule estimators for coefficients in a linear regression model when the disturbances are not necessarily normally distributed. It is shown that none of the two estimators dominates the other, except in the trivial case of merely one regression coefficient where least squares is found ...

In this paper, we obtain asymptotic formulas with error estimates for the implied volatility associated with a European call pricing function. We show that these formulas imply Lee’s moment formulas for the implied volatility and the tail-wing formulas due to Benaim and Friz. In addition, we analyze Pareto-type tails of stock price distributions in uncorrelated Hull-White, Stein-Stein, and Hest...

Dyslexia is a selective impairment of reading and spelling abilities without a deficit in general intelligence. Dyslexia is commonly attributed to a phonological deficits (e.g., Ramus, Rosen, Dakin, Day, Castellote, White & Frith, 2003). However, a mild cerebellum dysfunction (Nicolson, Fawcett & Dean, 2001) and specific visual problems, such as a defective magnocellular system, have also been ...

Este artículo discute las considerables semejanzas entre concepciones de la persona defendidas por Husserl, Scheler y Stein, según cuales es un valor absoluto que se ejercita en tomas posición. Para los fenomenólogos clásicos (Husserl, Stein), ética concierne a su totalidad, incluyendo dimensiones afectiva racional, el intelecto corazón, así como volición. Las personas distinguen agencia libre,...

AbstractIn this paper we formulate Stein–minimax type estimators and compare the performance properties with other estimators in case of mean value predictions. When the model is estimated by ordinary least squares it has been observed that least squares predicted is unbiased while minimax and Stein-minimax predictors are biased. The superiority conditions of the estimators have been derived by...

The numerical solution of Stein (aka discrete Lyapunov) equations is the primary step in Newton’s method for the solution of discrete-time algebraic Riccati equations (DARE). Here we present a low-rank Smith method as well as a low-rank alternating-direction-implicit-iteration to compute lowrank approximations to solutions of Stein equations arising in this context. Numerical results are given ...

A Stein covering of a complex manifold may be used to realise its analytic cohomology in accordance with the Čech theory. If, however, the Stein covering is parameterised by a smooth manifold rather than just a discrete set, then we construct a cohomology theory in which an exterior derivative replaces the usual combinatorial Čech differential. Our construction is motivated by integral geometry...
