Download or read book Modelling and Forecasting Financial and Economic Time Series Using Different Semiparametric ACD Models written by Sarah Forstinger and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The contents of this dissertation are on a semiparametric extension of the ACD model of Engle and Russell (1998). The proposal of the Semi-ACD model is based on the decomposition of the data of interest into a deterministic and a stochastic part, whereby the former is assumed to be time-varying. A non-negative, time-varying, smooth scale function is included into the model to take this into account, which is estimated with a local polynomial regression An automatic iterative plug-in bandwidth selection algorithm is developed. A simulation study evaluates the Semi-ACD model on the basis of various criteria. An extension of the proposal to log data shows that the estimation of the scale function is clearly simplified. In addition, decisive theoretical properties for the Semi-Log-ACD model are derived and the bandwidth selection algorithm is further automated. To forecast non-negative financial data, the above models are combined with known and new forecasting methods. In order to not limit the flexibility of the semiparametric idea, bootstrap methods are chosen as nonparametric forecasting methods. Compared to model-based Kalman filter predictions, these give not the best forecasts, but are clearly better compared to the corresponding parametric model forecasts. The algorithm is further applied to forecast the log-GDP of developing and developed countries. Random Walk models with a constant drift, a linear drift and a local linear drift are applied, as well. It is found that combining forecasting methods improves the forecasts and especially including the local linear regression method stabilizes the forecasts and enables the detection of variations in the trend process, that are typical for developing countries. Promising research questions to further improve the Semi-(Log-)ACD models are presented. ; eng

Download or read book A Semiparametric Smooth Transition Arx Model for Nonlinear Time Series written by Dimitrios D. Thomakos and published by . This book was released on 2005 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this paper, I propose an extension to the class of semiparametric time series models by incorporating a weight function to allow for smooth transitions between a linear autoregressive and a nonparametric component. The weight function and nonparametric component may depend on auxiliary variables. The inclusion of the weight function broadens the flexibility of the semiparametric model and allows for testing against smooth transition parametric models and against linearity. If no auxiliary variables are used the model is a special case of the functional coefficient autoregressive model, while if auxiliary variables are used the model's solution is a distributed lag in nonlinear functions. The nonparametric component is approximated using a Fourier series expansion and the model is estimated using the MINPIN approach proposed in Andrews (1994). An empirical illustration is provided using the U.S. quarterly unemployment rate data, previously analyzed in Montgomery et al. (1998).
Download or read book Modeling Discrete Time to Event Data written by Gerhard Tutz and published by Springer. This book was released on 2016-06-14 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on statistical methods for the analysis of discrete failure times. Failure time analysis is one of the most important fields in statistical research, with applications affecting a wide range of disciplines, in particular, demography, econometrics, epidemiology and clinical research. Although there are a large variety of statistical methods for failure time analysis, many techniques are designed for failure times that are measured on a continuous scale. In empirical studies, however, failure times are often discrete, either because they have been measured in intervals (e.g., quarterly or yearly) or because they have been rounded or grouped. The book covers well-established methods like life-table analysis and discrete hazard regression models, but also introduces state-of-the art techniques for model evaluation, nonparametric estimation and variable selection. Throughout, the methods are illustrated by real life applications, and relationships to survival analysis in continuous time are explained. Each section includes a set of exercises on the respective topics. Various functions and tools for the analysis of discrete survival data are collected in the R package discSurv that accompanies the book.

Download or read book Mixed Effects Models for Complex Data written by Lang Wu and published by CRC Press. This book was released on 2009-11-11 with total page 431 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although standard mixed effects models are useful in a range of studies, other approaches must often be used in correlation with them when studying complex or incomplete data. Mixed Effects Models for Complex Data discusses commonly used mixed effects models and presents appropriate approaches to address dropouts, missing data, measurement errors, censoring, and outliers. For each class of mixed effects model, the author reviews the corresponding class of regression model for cross-sectional data. An overview of general models and methods, along with motivating examples After presenting real data examples and outlining general approaches to the analysis of longitudinal/clustered data and incomplete data, the book introduces linear mixed effects (LME) models, generalized linear mixed models (GLMMs), nonlinear mixed effects (NLME) models, and semiparametric and nonparametric mixed effects models. It also includes general approaches for the analysis of complex data with missing values, measurement errors, censoring, and outliers. Self-contained coverage of specific topics Subsequent chapters delve more deeply into missing data problems, covariate measurement errors, and censored responses in mixed effects models. Focusing on incomplete data, the book also covers survival and frailty models, joint models of survival and longitudinal data, robust methods for mixed effects models, marginal generalized estimating equation (GEE) models for longitudinal or clustered data, and Bayesian methods for mixed effects models. Background material In the appendix, the author provides background information, such as likelihood theory, the Gibbs sampler, rejection and importance sampling methods, numerical integration methods, optimization methods, bootstrap, and matrix algebra. Failure to properly address missing data, measurement errors, and other issues in statistical analyses can lead to severely biased or misleading results. This book explores the biases that arise when naïve methods are used and shows which approaches should be used to achieve accurate results in longitudinal data analysis.
