Download E-books Bayesian Psychometric Modeling (Chapman & Hall/CRC Statistics in the Social and Behavioral Sciences) PDF

By Roy Levy, Robert J. Mislevy

A unmarried Cohesive Framework of instruments and systems for Psychometrics and Assessment

Bayesian Psychometric Modeling offers a unified Bayesian strategy throughout usually separate households of psychometric versions. It indicates that Bayesian recommendations, as choices to standard techniques, provide unique and profound merits achieve many ambitions of psychometrics.

Adopting a Bayesian technique can reduction in unifying likely disparate―and occasionally conflicting―ideas and actions in psychometrics. This e-book explains either how you can practice psychometrics utilizing Bayesian tools and why a number of the actions in psychometrics align with Bayesian thinking.

The first a part of the ebook introduces foundational rules and statistical types, together with conceptual concerns, general distribution versions, Markov chain Monte Carlo estimation, and regression. Focusing extra without delay on psychometrics, the second one half covers well known psychometric types, together with classical attempt conception, issue research, merchandise reaction conception, latent classification research, and Bayesian networks. during the e-book, approaches are illustrated utilizing examples essentially from academic checks. A supplementary site offers the datasets, WinBUGS code, R code, and Netica documents utilized in the examples.

Download E-books Ergodic Theory (Grundlehren der mathematischen Wissenschaften) PDF

Ergodic concept is among the few branches of arithmetic which has replaced noticeably over the last twenty years. sooner than this era, with a small variety of exceptions, ergodic conception dealt basically with averaging difficulties and common qualitative questions, whereas now it's a strong amalgam of tools used for the research of statistical houses of dyna­ mical platforms. consequently, the issues of ergodic concept now curiosity not just the mathematician, but in addition the learn employee in physics, biology, chemistry, and so on. the description of this ebook turned transparent to us approximately ten years in the past yet, for numerous purposes, its writing demanded an extended time period. the most precept, which we adhered to from the start, used to be to strengthen the techniques and techniques or ergodic conception within the learn of diverse concrete examples. due to this, half I of the publication includes the outline of varied periods of dynamical structures, and their user-friendly research at the foundation of the basic notions of ergodicity, blending, and spectra of dynamical structures. right here, as in lots of different situations, the adjective" undemanding" i~ no longer synonymous with "simple. " half II is dedicated to "abstract ergodic concept. " It comprises the construc­ tion of direct and skew items of dynamical structures, the Rohlin-Halmos lemma, and the idea of precise representations of dynamical platforms with non-stop time. a substantial half offers with entropy.

Download E-books The Humongous Book of Trigonometry Problems PDF

By W. Michael Kelley

So much math and technological know-how learn courses are a mirrored image of the varsity professors who write them-dry, tricky, and pretentious.

The Humongous e-book of Trigonometry Problems is the exception. writer Mike Kelley has taken what seems to be a standard trigonometry workbook, chock filled with solved difficulties — greater than 750! — and made notes within the margins including lacking steps and simplifying strategies and suggestions, so what will be baffling to scholars is made completely transparent. not will befuddled scholars ask yourself the place a selected solution got here from or need to depend on trial and blunder to resolve difficulties. And by means of studying the right way to interpret and clear up difficulties as they're offered in a customary trigonometry direction, scholars turn into totally ready to unravel these tricky, imprecise difficulties that have been by no means mentioned in school yet consistently appear to locate their method onto exams.

Download E-books Mathematische Statistik I: Parametrische Verfahren bei festem Stichprobenumfang (German Edition) PDF

Empirische Forschung ist heutzutage ohne die Verwendung von Schlußweisen der Statistik nicht mehr denkbar. Dementsprechend existiert eine umfangreiche statistische Lehrbuchliteratur, die sich jedoch bis auf wenige Ausnahmen in eine der folgenden vier Gruppen einordnen läßt: 1) Einführende Lehrbücher auf mathematisch elementarem Niveau, 2) Bücher, die sich an den mathematisch weniger geschulten Anwender richten und in denen Verfahren der Statistik lediglich beschrieben bzw. aus der Sicht des Praktikers kommentiert werden, three) Monographien über engbegrenzte Spezialgebiete, four) Werke, die in mathematisch-abstrakter Behandlung allgemeine Theorien statistischer Entscheidungen entwickeln. Während die Bücher der ersten beiden Kategorien kaum Verständnis etwa dafür wecken können, wie die speziellen Modellannahmen in ein statistisches Verfahren eingehen oder welches Konstruktionsprinzip einem bestimmten Verfahren zugrunde liegt, setzen umgekehrt die Bücher der beiden letztgenannten Gruppen - ebenso wie Originalliteratur - ein derartiges Verständnis wie zumeist auch eine Vertrautheit mit den umfangreichen technischen Hilfsmitteln der Mathematischen Statistik bereits voraus. Dieser umfangreichen Literatur steht nur eine vergleichsweise geringe Zahl solcher Bücher gegenüber, die sich an Leser wenden, die zwar noch keinerlei Kenntnisse auf dem Gebiet der Mathematischen Statistik besitzen, die aber über eine mathematische Grundausbildung etwa in dem Umfang verfügen, wie sie an den Universitäten im deutschsprachigen Raum bis zum Vordiplom vermittelt wird. In dem zwei bändigen Werk, dessen erster Teil nunmehr vorliegt, werden auf mittlerer mathematischer Ebene Standardfragestellungen der Statistik behandelt. Insbesondere sollen zu intuitiv nahe­ liegenden Optimalitätskriterien konkrete attempt- und Schätzverfahren vermöge geeigneter Konstruktionsprinzipien hergeleitet werden.
