Nonparametric Estimation and Hypothesis Testing in Econometric Models by A. Ullah

...empec, Vol. 13, 1988, page 223-249 Nonparametric Estimation and Hypothesis Testing in Econometric Models By A. Ullah ~ Abstract: In this paper we systematically review and develop nonparametric estimation and testing techniques in the context of econometric models. The results are discussed under the settings of regression model and kernel estimation, although as indicated in the paper these results can go through for other econometric models and for the nearest neighbor estimation. A nontechnical survey of the asymptotic properties of kernel regression estimation is also presented. The technique described in the paper are useful for the empirical analysis of the economic relations whose true functional forms are usually unknown. 1 Introduction Consider an economic model y =R(x)+u where y is a dependent variable, x is a vector o f regressors, u is the disturbance and R(x) = E ( y l x ) . Often, in practice, the estimation o f the derivatives o f R(x)are o f interest. For example, the first derivative indicates the response coefficient (regression coefficient) o f y with respect to x, and the second derivauve indicates the curvature o f R(x).

Using Uml to Model System

...INTRODUCTION This IDoc describes use of the Unified Modeling Language (UML) to model and document Accounting Information Systems (AIS). The objective of modeling AIS is multifaceted and can be to: visualize, understand, summarize, detail, analyze, design, develop, implement, operate, secure, control, or audit the AIS. UML is a powerful modeling language and technique for all of these modeling tasks and is more robust and semantically superior to the commonly used Structured Analysis (SA) modeling tools of flowcharts (FC), data flow diagrams (DFD), and entity-relationship diagrams (ERD). Dr. White suggests that using UML diagrams as a tool to document AIS is a viable alternative to the Structured Analysis’s diagrams of FC, DFD, and ERD. What follows in Section II is a brief comparison of the two alternative approaches to systems documentation: Structured Analysis (SA) and Object Orientation (OO). Section III presents the definition and description of the major structural and behavioral elements used in UML including classifiers, instances, relationships, collaborations, activities, interactions, and states. Section IV discusses the organization and presentation of UML documentation of AIS as a collection of diagrams and packages. Section V contains various UML diagrams of the business revenue cycle (system) as examples of how to use UML to document a business system. Section VI contains examples of UML models of two special systems of great importance to accountants:......

A Novel Channel Estimation Algorithm for 3gpp Lte Downlink System Using Joint Time-Frequency Two-Dimensional Iterative Wiener Filter

...A Novel Channel Estimation Algorithm for 3GPP LTE Downlink System Using Joint Time-Frequency Two-Dimensional Iterative Wiener Filter Jinfeng Hou, Jian Liu School of Communication and Information Engineering University of Electronic Science and Technology of China (UESTC) Chengdu 611731, China Email: houjinfeng@gmail.com, liuj@uestc.edu.cn Abstract—The channel estimation algorithms are employed in 3GPP Long Term Evolution (LTE) downlink system to assist the coherent demodulation of Orthogonal Frequency Division Multiplexing (OFDM) symbols. Based on the comparison of several exiting different channel estimation algorithms, we propose a joint time-frequency two-dimensional iterative Wiener filter (IWF) channel estimation algorithm for 3GPP LTE downlink system. In this scheme, we first apply the linear minimum mean square error (LMMSE) algorithm based on singular value decomposition (SVD) for IWF in frequency domain, and then the values after the first filtering in frequency domain are used to achieve the second IWF in time domain. Comparing to the conventional algorithms, the channel estimation algorithm proposed by this paper brings up lower bit error rate (BER) and adds little computational complexity. I. I NTRODUCTION In December 2004, the Third Generation Partnership Program (3GPP) members started a feasibility study on the enhancement of the Universal Terrestrial Radio Access (UTRA) in the aim of continuing the long time frame competitiveness of the 3G Universal Mobile......

Model Checking Using Pat

...Automatic Model Checking of State Machines A seminar report submitted to MANIPAL UNIVERSITY For Partial Fulfillment of the Requirement for the Award of the Degree of Master of Technology in Software Engineering by Anusha A Reg. No. 130928001 February 2014 Abstract The idea of Model Driven Development (MDD) is to specify requirements of systems in a formal (usually graphical) notation. UML is the initial and dominant modelling phase in software engineering arena. If errors are occurring in this phase of software development itself, it will cost a lot. Hence it is crucial to detect model level errors in the initial phase rather than later stages of software development. An approach to automatically verifying models composed of UML state machines. This approach helps in checking safety/liveness, properties, trace refinement, relationships and so on with the help of PAT (Process Analysis Toolkit) and CSP (communicating sequential programs). 1 1 1.1 Introduction State Machines The concepts behind state machines are about organizing the way a device, computer program, or other (often technical) process works such that an entity or each of its sub-entities is always in exactly one of a number of possible states and where there are well-defined conditional transitions between these states. The UML state diagrams are directed graphs in which nodes denote states and connectors denote state transitions. In UML, states are represented as rounded rectangles......

Explanation of Industry Returns Using the Variable Beta Model and Lagged Variable Beta Model

...Journal Of Financial And Strategic Decisions Volume 8 Number 2 Summer 1995 EXPLANATION OF INDUSTRY RETURNS USING THE VARIABLE BETA MODEL AND LAGGED VARIABLE BETA MODEL Thomas M. Krueger* and Mohammad H. Rahbar* Abstract Beta is found to be a function of several leading economic indicators and government policy variables within the context of the Variable Beta Model which incorporates economic characteristics in the single index model in a multiplicative manner. When contemporaneous macroeconomic descriptors are replaced with reporting-period-lagged macroeconomic descriptors, in the Lagged Variable Beta Model, model explanatory power increases. Findings suggest that the lagged beta model is more likely to satisfy the ordinary least squares assumptions of serially independent error terms. INTRODUCTION Beta as a measure of priced risk is again under attack. Fama and French's [10,11] finding that the single index market model (SIMM) does not describe the last 50 years of average stock returns has been widely reported. Such a finding has widespread implications for corporate finance and investment management. Capital budgeting has frequently been based upon the belief that a higher return was required from projects with more volatile cash flows under the assumption that the volatile cash flows are at least partially dependent upon systematic factors. Firms which have based a portion of their appeal on the basis of their high beta and assumed higher rates of return may......

Tra Using Advice Model

...Introduction TRA is an acronym that means Transfer, Retention and Application. TRA could be done using ADVISE model. ADVISE is an acronym that means: • A for analytical learning. • D for Descriptive learning. • V for Visualization of ideas. • I for Interactive assessment. • S for Split testing. • E for Experiential learning. TRA Transfer Knowledge is being transfer to the student using different methods as video and case studies and presentations. Presentations and videos are powerful tools that helped me in the past to gain the knowledge I need. Retention Group discussion in my opinion is useful method that helps retaining knowledge and information. Application I found through practice the best way to retain knowledge is to apply it in real situation or teaching it to others. ADVICE Model I recently encountered at work an incident that I had to investigate the reason for failing proficiency. Using Root cause analysis method (RCA) I first analyze the steps being involved in processing the proficiency samples starting from receiving to reporting the results to NYSDOH. I also had to interact with the people who handled the specimens. I found out the specimens was stored correctly upon receiving than was ordered in the system and labeled correctly. I looked at all variables that could affect testing process, from temperature, human error, reagents and quality controls. I questioned the technologist who ran the specimen on the steps he did to analyze the......

Using a Valuation Model to Estimate a Firm's Stock Price

...[pic] Michael G. Foster School of Business Using a Valuation Model to Estimate a Firm’s Stock Price* In the ongoing search for bargains in the stock market, analysts and investors rely on models to estimate the intrinsic value of a firm’s equity. By comparing the valuation suggested by their model to the actual value in the marketplace, they form opinions as to whether a given stock is under or over valued. Valuation models are also used by investment bankers as an aid to pricing initial public offerings, and to inform parties involved in assorted private transactions such as selling a business or division, dividing property among owners, and settling estates. In this note, we introduce a relatively simple but powerful model of equity (stock) valuation.[1] 1. The basic idea behind valuation Valuation models in finance are typically based on discounted future cash flows or discounted future dividends. Keep in mind that, holding underlying assumptions constant, all valuation models should yield the same result. A model for valuing equity based on accounting data may be preferable in some cases, in that: o Benchmarks for performance are almost always given in earnings per share (EPS) – not cash flows or dividends. o Since real world dividend payout policies tend to be stable for long periods, valuation models based on dividends are less useful for modeling changes in value. o Earnings generally receive far more attention from the......

Relfective Using Gibbs Model

...reflection is important whereby it helps to identify strengths and weaknesses. Jarvis (1992) mentioned that reflective practice can also be known as a learning process through and from the experiences towards gaining new ideas. The two type of reflective practice by Schon (1987) are the capacity in reflecting in action and on reflecting on action. Based on Schon (1987) theory reflection in action is a process which allows us to reshape what we are working on, while we are working on it. On the other hand, reflecting on action and thinking back on what we have done in order to discover how our knowing in action may have contributed to an unexpected outcome. There are many types of reflective theory to reflect on action. Gibbs Model of Reflection is a common model of reflection that is used within the health professions. It consists of 6 stages which are descriptive, feelings, evaluation, analysis, conclusion and action plan.

Comparative Ultrastructural Analyses of Platelets and fibrin Networks Using the Murine Model of Asthma

...ARTICLE IN PRESS Experimental and Toxicologic Pathology 59 (2007) 105–114 www.elsevier.de/etp Comparative ultrastructural analyses of platelets and fibrin networks using the murine model of asthma E. PretoriusÃ, O.E. Ekpo, E. Smit Department of Anatomy, School of Health Sciences, Faculty of Health Sciences, University of Pretoria, BMW Building, P.O. Box 2034, Pretoria 0001, South Africa Received 10 October 2006; accepted 13 February 2007 Abstract The murine Balb/c asthma model has been used successfully for a number of in vivo immunological applications and for testing novel therapeutics, and it is a reliable, clinically relevant facsimile of the human disease. Here we investigate whether this model can be used to study other components of the human body, e.g. ultrastrucure. In particular, we investigate the effect of the phytomedicine Euphorbia hirta (used to treat asthma), on the ultrastructure of fibrin as well as platelets, cellular structures that both play an important role in the coagulation process. Hydrocortisone is used as positive control. Ultrastructure of the fibrin networks and platelets of control mice were compared to mice that were asthmatic, treated with two concentrations of hydrocortisone and one concentration of the plant material. Results indicate control mice possess major, thick fibers and minor thin fibers as well as tight round platelet aggregates with typical pseudopodia formation. Minor fibers of asthmatic mice have a netlike appearance......
