  • Statistical procedures of estimation and inference are most frequently justified in econometric work on the basis of certain desirable asymptotic properties. One estimation procedure may, for example, be selected over another because it is known to provide consistent and asymptotically efficient parameter estimates under certain stochastic environments.

  • This is a survey of non-linear regression models, with an emphasis on the theory of estimation and hypothesis testing rather than computation and applications, although there will be some discussion of the last two topics. For a general discussion of computation the reader is referred to Chapter 12 of this Handbook by Quandt. My aim is to present the gist of major results; therefore, I will sometimes omit proofs and less significant assumptions. For those, the reader must consult the original sources....

  • From the system we call the ‘normal equation system’ we can solve K normal equations for K unknown beta coefficients. The straight-forward representation of the solution is expressed in the matrix algebra. However, since the main purpose is the application and EViews. Other data analysis software is available, so we can easily find regression coefficients without remembering all the algebraic expressions.

  • Partial differential equations (PDEs) are very important in modelling as their solutions unlock the secrets to a range of important phenomena in engineering and physics. The PDE known as the wave equation models sound waves, light waves and water waves. It arises in fields such as acoustics, electromagnetics and fluid dynamics.

  • In addition to covering statistical methods, most of the existing books on equating also focus on the practice of equating, the implications of test development and test use for equating practice and policies, and the daily equating challenges that need to be solved. In some sense, the scope of this book is narrower than of other existing books: to view the equating and linking process as a statistical estimation task.

  • The existence problem is solved, and global pointwise estimates of solutions are obtained for quasilinear and Hessian equations of Lane-Emden type, including the following two model problems: −∆p u = uq + µ, Fk [−u] = uq + µ, u ≥ 0, on Rn , or on a bounded domain Ω ⊂ Rn . Here ∆p is the p-Laplacian defined by ∆p u = div ( u| u|p−2 ), and Fk [u] is the k-Hessian defined as the sum of k × k principal minors of the Hessian matrix D2 u (k = 1, 2, . . . ,...

  • We use these theoretical underpinning to specify estimable equations for the supply of and demand for corporate credit. Since theory does not provide clues as to the possible structural forms of these equations we basically rely on reduced forms. Data considerations, in particular, the availability of relevant statistical data, also has played a certain role in the specification of these equations.

  • The Dictionary of Nursing Theory and Research provides a compilation of definitions and discussions of terms that are commonly encountered in the nursing literature. In this third edition of our dictionary we have retained and revised most of the terms in the earlier versions and have added many new ones. The new terms are in response to evolutionary changes that have occurred over the intervening years. We have added entries for evidence-based practice and Internet research.

  • We have attempted to improve and update this text while retaining the features that make it unique, namely, an emphasis on physical understanding, and the ability to estimate, evaluate, and predict results without blind reliance on computers, while still maintaining rigorous connection to the mathematical basis for quantum chemistry. We have inserted intomost chapters examples that allowimportant points to be emphasized, clarified, or extended. This has enabled us to keep intact most of the conceptual development familiar to past users.

  • Computers are one of the most important tools in any field of science and especially in physics. A student in an undergraduate lab will appreciate the help of a computer in calculating a result from a series of measurements. The more advanced researcher will use them for tasks like simulating an experiment, or solving complex systems of equations. Physics is deeply connected to mathematics and requires a lot of calculational skills. If one is only interested in a conceptual understanding of the field, or an estimate of the outcome of an experiment, simple calculus will probably suffice.

  • In this paper, we prove global second derivative estimates for solutions of the Dirichlet problem for the Monge-Amp`re equation when the inhomogee neous term is only assumed to be H¨lder continuous. As a consequence of our o approach, we also establish the existence and uniqueness of globally smooth solutions to the second boundary value problem for the affine maximal surface equation and affine mean curvature equation.

  • The potential evapotranspiration can be directly calculated by the Penman-Monteith equation, known as the one-step method. The approach requires data on the land cover and relatedvegetation parameters based on AVHRR and LDAS information, which are available in recent years. The Nong Son Basin, a sub-catchment of the Vu Gia - Thu Bon Basin in the Central Vietnam, is selected for this study. To this end, NAM model was used; the obtained results show that the NAM model has a potential to reproduce the effects of potential...

  • This is the first in a series of papers in which we initiate the study of very rough solutions to the initial value problem for the Einstein-vacuum equations expressed relative to wave coordinates. By very rough we mean solutions which cannot be constructed by the classical techniques of energy estimates and Sobolev inequalities. Following [Kl-Ro] we develop new analytic methods based on Strichartz-type inequalities which result in a gain of half a derivative relative to the classical result. ...

  • To estimate equation (5) we have to take into account the potential endogeneity of financial performance and board appointment decisions. Furthermore, including the lagged dependent variable as an independent variable makes the fixed effects estimator not only biased, but also inconsistent. To overcome this problem an instrumental variables (IV) estimator could be used. However, appropriate governance instruments are not easy to find.
