Testing Primitive Polynomials for Generalized Feedback Shift Register Random Number Generators

Lian, Guinan 30 November 2005 (has links) (PDF)
The class of generalized feedback shift register (GFSR) random number generators was a promising method for random number generation in the 1980's, but was abandoned because of some flaws such as poor performance on certain tests for randomness. The poor performance may be due to the choice of primitive polynomials used in the generators, rather than inherent flaws in the method. The original GFSR generators were all based on primitive trinomials. This project examines several alternative choices of primitive polynomials with more than one "interior" term to address this problem and hopefully provide access to good random number generators.

Métodos de diagnóstico em modelos logísticos trinomiais / Methods of dignóstics in trinomials Logistic models

Silva, Jose Alberto Pereira da 10 October 2003 (has links)
Os modelos logísticos trinomiais podem ser interpretados como uma extensão natural do modelo logístico binomial para situações em que a resposta admite apenas três resultados. Introduzimos inicialmente os modelos logísticos trinomiais e discutiremos em seguida alguns aspectos inferenciais, tais como estimação e testes. Medidas de qualidade do ajuste são também apresentadas. Contudo, o principal foco deste trabalho é a apresentação de métodos de diagnóstico. Mostramos que as técnicas usuais de diagnóstico desenvolvidas para o modelo logístico binomial podem ser adaptadas para o caso trinomial. O desenvolvimento de métodos diretos para o modelo logístico trinomial é mais complexo do ponto de vista computacional, embora seja sempre possível. Discutimos alguns desses métodos, dentre os quais, o desenvolvimento de resíduos, de métodos para detectar pontos de alavanca, métodos de deleção de pontos e influência local. Comparamos os métodos adaptados com alguns métodos diretos através de exemplos. / The trinomial logistic models can be interpreted as a natural extension of the traditional binomial logistic model to situations in which the response allows only three possible results. We firts introduce the trinomial logistic modles and then some inferential aspects, such as estimation and hypothesis testing are discussed. Good-of-fit measures are also given. However, the aim of this work is the presentation of some diagnostic procedures for trinomial logistic models. We show that methods developed for binomial logistic models can adapted straightforward for trinomial models. The developement of direct methods, even though possible, in general requires more complex calculation. Some of these direct methods, suchs as evaluation of residuals, measures of high leverage points, deletion methods and local influence are apresented. Coparisons between adapted and direct methods are made via examples with real data.
