This book was released on 2013-04-01 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les projets informatiques sont désormais développés dans le cadre d’un système existant. Ils doivent, in fine, s’intégrer en interaction avec d’autres projets, sur les infrastructures communes de l’entreprise et sans interrompre le service : c’est la notion d’usine logicielle. Estimation des projets de l’entreprise numérique s’intéresse particulièrement à l’analyse des coûts d’intégration. Un modèle original d’estimation de ces coûts est proposé assurant l’équilibrage des quatre grandeurs fondamentales : coût, qualité, fonctionnalité et délai. Cet ouvrage bénéficie des travaux effectués par le groupe de travail Intégration & Complexité de l’association CESAMES, en relation avec la chaire X-ParisTech, ce qui a permis de valider le modèle avec les industriels participants. Il présente en détail le modèle COCOMO et dresse les grandes lignes de la méthode de comptage par points de fonctions. Une étude de cas basée sur les systèmes C4ISTAR illustre l’utilisation de ces méthodes dans un contexte de systèmes réels de grande complexité.

Available in PDF, EPUB and Kindle. Book excerpt: " If you have trouble estimating cost or schedule for your projects, you are not alone. The question is this: who wants the estimate and why? The definition of estimate is to guess. But too often, the people who want estimates want commitments. Instead of a commitment, you can apply practical and pragmatic approaches to developing estimates and then meet your commitments. You can provide your managers with the information they want and that you can live with. Learn how to use different words for your estimates and how to report an estimate that includes uncertainty. Learn who should and should not estimate. Learn how to update your estimate when you know more about your project. Regain estimation sanity. Learn practical and pragmatic ways to estimate schedule or cost for your projects. "

Available in PDF, EPUB and Kindle. Book excerpt: The application of estimation theory renders the processing of experimental results both rational and effective, and thus helps not only to make our knowledge more precise but to determine the measure of its reliability. As a consequence, estimation theory is indispensable in the analysis of the measuring processes and of experiments in general.The knowledge necessary for studying this book encompasses the disciplines of probability and mathematical statistics as studied in the third or fourth year at university. For readers interested in applications, comparatively detailed chapters on linear and quadratic estimations, and normality of observation vectors have been included. Chapter 2 includes selected items of information from algebra, functional analysis and the theory of probability, intended to facilitate the reading of the text proper and to save the reader looking up individual theorems in various textbooks and papers; it is mainly devoted to the reproducing kernel Hilbert spaces, helpful in solving many estimation problems. The text proper of the book begins with Chapter 3. This is divided into two parts: the first deals with sufficient statistics, complete sufficient statistics, minimal sufficient statistics and relations between them; the second contains the mostimportant inequalities of estimation theory for scalar and vector valued parameters and presents properties of the exponential family of distributions.The fourth chapter is an introduction to asymptotic methods of estimation. The method of statistical moments and the maximum-likelihood method are investigated. The sufficient conditions for asymptotical normality of the estimators are given for both methods. The linear and quadratic methods of estimation are dealt with in the fifth chapter. The method of least squares estimation is treated. Five basic regular versions of the regression model and the unified linear model of estimation are described. Unbiased estimators for unit dispersion (factor of the covariance matrix) are given for all mentioned cases. The equivalence of the least-squares method to the method of generalized minimum norm inversion of the design matrix of the regression model is studied in detail. The problem of estimating the covariance components in the mixed model is mentioned as well. Statistical properties of linear and quadratic estimators developed in the fifth chapter in the case of normally distributed errors of measurement are given in Chapter 6. Further, the application of tensor products of Hilbert spaces generated by the covariance matrix of random error vector of observations is demonstrated. Chapter 7 reviews some further important methods of estimation theory. In the first part Wald's method of decision functions is applied to the construction of estimators. The method of contracted estimators and the method of Hoerl and Kennard are presented in the second part. The basic ideas of robustness and Bahadur's approach to estimation theory are presented in the third and fourth parts of this last chapter.

Download or read book Applied Optimal Estimation written by The Analytic Sciences Corporation and published by MIT Press. This book was released on 1974-05-15 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first book on the optimal estimation that places its major emphasis on practical applications, treating the subject more from an engineering than a mathematical orientation. Even so, theoretical and mathematical concepts are introduced and developed sufficiently to make the book a self-contained source of instruction for readers without prior knowledge of the basic principles of the field. The work is the product of the technical staff of The Analytic Sciences Corporation (TASC), an organization whose success has resulted largely from its applications of optimal estimation techniques to a wide variety of real situations involving large-scale systems. Arthur Gelb writes in the Foreword that "It is our intent throughout to provide a simple and interesting picture of the central issues underlying modern estimation theory and practice. Heuristic, rather than theoretically elegant, arguments are used extensively, with emphasis on physical insights and key questions of practical importance." Numerous illustrative examples, many based on actual applications, have been interspersed throughout the text to lead the student to a concrete understanding of the theoretical material. The inclusion of problems with "built-in" answers at the end of each of the nine chapters further enhances the self-study potential of the text. After a brief historical prelude, the book introduces the mathematics underlying random process theory and state-space characterization of linear dynamic systems. The theory and practice of optimal estimation is them presented, including filtering, smoothing, and prediction. Both linear and non-linear systems, and continuous- and discrete-time cases, are covered in considerable detail. New results are described concerning the application of covariance analysis to non-linear systems and the connection between observers and optimal estimators. The final chapters treat such practical and often pivotal issues as suboptimal structure, and computer loading considerations. This book is an outgrowth of a course given by TASC at a number of US Government facilities. Virtually all of the members of the TASC technical staff have, at one time and in one way or another, contributed to the material contained in the work.

Download or read book Estimation in Semiparametric Models written by Johann Pfanzagl and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Assume one has to estimate the mean J x P( dx) (or the median of P, or any other functional t;;(P)) on the basis ofi.i.d. observations from P. Ifnothing is known about P, then the sample mean is certainly the best estimator one can think of. If P is known to be the member of a certain parametric family, say {Po: {) E e}, one can usually do better by estimating {) first, say by {)(n)(.~.), and using J XPo(n)(;r.) (dx) as an estimate for J xPo(dx). There is an "intermediate" range, where we know something about the unknown probability measure P, but less than parametric theory takes for granted. Practical problems have always led statisticians to invent estimators for such intermediate models, but it usually remained open whether these estimators are nearly optimal or not. There was one exception: The case of "adaptivity", where a "nonparametric" estimate exists which is asymptotically optimal for any parametric submodel. The standard (and for a long time only) example of such a fortunate situation was the estimation of the center of symmetry for a distribution of unknown shape.

Available in PDF, EPUB and Kindle. Book excerpt: The generalized method of moments (GMM) estimation has emerged as providing a ready to use, flexible tool of application to a large number of econometric and economic models by relying on mild, plausible assumptions. The principal objective of this volume is to offer a complete presentation of the theory of GMM estimation as well as insights into the use of these methods in empirical studies. It is also designed to serve as a unified framework for teaching estimation theory in econometrics. Contributors to the volume include well-known authorities in the field based in North America, the UK/Europe, and Australia. The work is likely to become a standard reference for graduate students and professionals in economics, statistics, financial modeling, and applied mathematics.

Les cinq manuels de la collection Évaluations nationales des acquis scolaires introduisent les concepts clés des évaluations nationales du niveau de performances des élèves, dont les questions politiques à traiter dans la conception et la mise en 'uvre des évaluations ou le développement d'un test, la conception d'un questionnaire, l'échantillonnage, l'organisation et la mise en 'uvre de la collecte de données, le nettoyage et l'analyse statistique des données, la rédaction de rapports et l'exploitation des résultats pour améliorer la qualité de l'éducation. Qu'apprennent les élèves ' Dans le monde, les gouvernements qui aspirent à améliorer la qualité de l'éducation se tournent vers les évaluations nationales pour obtenir ces informations si précieuses dans les domaines clés des programmes de cours. La capacité à mener des évaluations nationales s'est remarquablement renforcée ces dernières années, mais l'utilisation généralisée des conclusions n'a pas suivi. Ce manuel vise à démontrer la valeur essentielle de ces données et à assister les pays dans l'exploitation des connaissances issues des évaluations nationales. Communiquer et utiliser les résultats d'une évaluation nationale des acquis scolaires recense les principaux facteurs qui affectent l'utilisation des constatations des évaluations nationales. Ceux-ci comprennent le contexte politique dans lequel une évaluation est menée, la nature de l'évaluation (sur la base d'un recensement ou d'un échantillon), les responsabilités de chacun vis-à -vis des résultats, et la qualité des instruments d'évaluation. Le manuel décrit le type d'informations requises dans le rapport principal d'une évaluation nationale, et d'autres moyens de communiquer les conclusions aux publics techniques et non techniques. Il énonce les principes généraux à suivre pour traduire les résultats des évaluations nationales dans le cadre de politiques et de mesures, et examine les procédures spécifiques d'utilisation des données dans l'élaboration de politiques, la gestion de l'éducation, l'enseignement et la promotion de la sensibilisation du public. Les thèmes traités dans ce volume sont de nature à intéresser les responsables des politiques, les équipes pédagogiques, les chercheurs et les professionnels du développement.
