  • 财务金融建模

    作者:(美)本尼卡

    《财务金融建模》在理论与实践之间架起了一座桥梁,它提供了运用Excel电子表解决一般财务与金融建模问题的具体操作过程,告诉读者每个模型的实现步骤,说明了它们是如何用Excel来求解的。 期待已久的这部标准教科书的第三版继承了财务金融“食谱大全”和使用Excel工具的特点。这也是第一版和第二版之所以备受欢迎的原因。此外它还增加了非常新的内容,这些新章节涉及的主题包括:银行估值、最优化投资组合的Black-Litterman方法、蒙特卡罗方法及其在期权定价中的应用,以及数组函数和公式的使用;其他的章节包括:基本的财务计算、投资组合模型、计算方差—协方差矩阵,以及随机数生成。以上内容经过了修订,并采用了许多全新和已改进的资料。其他涉及领域包括:财务报表建模、租赁、标准的投资组合问题、受险价值、久期与免疫策略、期限结构建模。技术章节涉及的主题包括:模拟运算表、矩阵、高斯一塞德尔方法,以及使用Excel的提示。最后一部分内容涉及本书所需要的VBA技术。 本书光盘中含有各章例题的Excel工作表和习题解答。
  • Agent-Based and Individual-Based Modeling

    作者:Steven F. Railsback,

    Product Description Agent-based modeling is a new technique for understanding how the dynamics of biological, social, and other complex systems arise from the characteristics and behaviors of the agents making up these systems. This innovative textbook gives students and scientists the skills to design, implement, and analyze agent-based models. It starts with the fundamentals of modeling and provides an introduction to NetLogo, an easy-to-use, free, and powerful software platform. Nine chapters then each introduce an important modeling concept and show how to implement it using NetLogo. The book goes on to present strategies for finding the right level of model complexity and developing theory for agent behavior, and for analyzing and learning from models. Agent-Based and Individual-Based Modeling features concise and accessible text, numerous examples, and exercises using small but scientific models. The emphasis throughout is on analysis--such as software testing, theory development, robustness analysis, and understanding full models--and on design issues like optimizing model structure and finding good parameter values. The first hands-on introduction to agent-based modeling, from conceptual design to computer implementation to parameterization and analysis Filled with examples and exercises, with updates and supplementary materials at www.railsback-grimm-abm-book.com Designed for students and researchers across the biological and social sciences Written by leading practitioners From the Inside Flap "Railsback and Grimm provide a needed book on how to develop, code, and analyze agent-based models. They so expertly explain the art and science of modeling that even the most modeling-shy beginner will master the skills. Readers will also gain a deep understanding of the increasing importance of agent-based models for interpreting the patterns of nature and human society."--Donald L. DeAngelis, U.S. Geological Survey "Railsback and Grimm have written a superb introduction to agent-based models. They combine hands-on programming exercises, introductions to some of the core concepts in complex systems, and instruction in model design and analysis. The result is an excellent book that's ideal for both undergraduates and academics."--Scott E. Page, author of Diversity and Complexity "Knitting together ecology, economics, and social systems, this wonderful book will encourage and enlighten novices and experienced modelers alike. It highlights the importance of patterns at every level of the modeling process, the need for clear explication of assumptions, and the benefits of models composed of discrete entities (agents) which interact, evolve, and mimic reality."--Louis Gross, University of Tennessee, Knoxville "This exceptional book offers a systematic introduction to the scientific use of agent-based modeling, including the implementation, testing, and validation of models. Until now there was no good textbook available to teach students the theory and practice of agent-based modeling. Railsback and Grimm provide such a text, one that will likely become a classic in the field."--Marco A. Janssen, Arizona State University "This book is an invaluable guide to agent-based modeling. A significant contribution to the field, it will train the next generation of modelers and teach best practices to existing modelers. Railsback and Grimm have in-depth expertise and experience in developing and teaching agent-based modeling, and are well qualified to write such a book."--Richard Stillman, Bournemouth University
  • Data Analysis Using Regression and Multilevel/Hierarchical Models

    作者:Andrew Gelman,Jennif

    Data Analysis Using Regression and Multilevel/Hierarchical Models is a comprehensive manual for the applied researcher who wants to perform data analysis using linear and nonlinear regression and multilevel models. The book introduces a wide variety of models, whilst at the same time instructing the reader in how to fit these models using available software packages. The book illustrates the concepts by working through scores of real data examples that have arisen from the authors' own applied research, with programming codes provided for each one. Topics covered include causal inference, including regression, poststratification, matching, regression discontinuity, and instrumental variables, as well as multilevel logistic regression and missing-data imputation. Practical tips regarding building, fitting, and understanding are provided throughout. Author resource page: http://www.stat.columbia.edu/~gelman/arm/
