This book presents some post-estimation and predictions strategies for the host of useful statistical models with applications in data science. It combines statistical learning and machine learning techniques in a unique and optimal way. It is well-known that machine learning methods are subject to many issues relating to bias, and consequently the mean squared error and prediction error may explode. For this reason, we suggest shrinkage strategies to control the bias by combining a submodel selected by a penalized method with a model with many features. Further, the suggested shrinkage methodology can be successfully implemented for high dimensional data analysis. Many researchers in statis...
A obra contempla ferramentas para o conhecimento das principais metodologias de análises de dados categóricos em variáveis resposta e variáveis explicativas, apresentando passos iniciais, dados organizados em tabelas de contingência, testes de independência, modelos generalizados, modelos para dados longitudinais, abordagem pré e pós testes, exemplos de aplicação e condução usando o ambiente computacional R.
This Open Access Brief presents the KAPSARC Global Energy Macroeconometric Model (KGEMM). KGEMM is a policy analysis tool for examining the impacts of domestic policy measures and global economic and energy shocks on the Kingdom of Saudi Arabia. The model has eight blocks (real sector, fiscal, monetary, external sector, price, labor and wages, energy, population, and age cohorts) that interact with each other to represent the Kingdom’s macroeconomy and energy linkages. It captures New Keynesian demand-side features anchored to medium-run equilibrium and long-run aggregate supply. It applies a cointegration and equilibrium correction modeling (ECM) methodology to time series data to estimat...
The book is an authoritative collection of contributions by leading experts on the topics of fuzzy logic, multi-valued logic and neural network. Originally written as an homage to Claudio Moraga, seen by his colleagues as an example of concentration, discipline and passion for science, the book also represents a timely reference guide for advance students and researchers in the field of soft computing, and multiple-valued logic.
Este livro, um sólido balanço da situação atual da educação superior no Brasil, reúne pesquisas desenvolvidas desde 2001 pelo Observatório Universitário – um núcleo de pesquisas da Universidade Candido Mendes dedicado ao estudo das políticas públicas dirigidas ao setor.Coordenado por Edson de Oliveira Nunes, o Observatório Universitário tem atuado em diversas frentes e se firmou como referência nacional para o debate sobre a educação superior: apesar de sua vocação acadêmica e do caráter técnico de seus trabalhos, também desenvolveu pesquisas aplicadas e prestou serviços a diferentes instituições educacionais, órgãos públicos e privados. No período de 2002 a 2...
Atopic dermatitis (eczema) is one of the most common and most challenging skin conditions, for patients and practitioners alike. Uniquely organized by intrinsic and extrinsic etiologies, Atopic Dermatitis: Inside Out or Outside In? examines a myriad of causes that start from both the inside of the body and from the external environment, offering physicians practical ways to design treatments that specifically address these causes. Drs. Lawrence S. Chan and Vivian Y. Shi, along with a team of expert contributing authors, examine the etiology of this complex disorder and provide targeted, comprehensive solutions and the most useful therapeutic plans based on pathophysiology, including evidence...
