Data analysts will learn how to incorporate nonlinearity in one or more predictor variables into regression models for different types of outcome variables. Such nonlinear dependence is often not considered in applied research, yet nonlinear relationships are common and so need to be addressed. A standard linear analysis can produce misleading conclusions, while a nonlinear analysis can provide novel insights into data, not otherwise possible.A variety of examples of the benefits of modeling nonlinear relationships are presented throughout the book. Methods are covered using what are called fractional polynomials based on real-valued power transformations of primary predictor variables combined with model selection based on likelihood cross-validation. The book covers how to formulate and conduct such adaptive fractional polynomial modeling in the standard, logistic, and Poisson regression contexts with continuous, discrete, and counts outcomes, respectively, either univariate or multivariate. The book also provides a comparison of adaptive modeling to generalized additive modeling (GAM) and multiple adaptive regression splines (MARS) for univariate outcomes.The authors have created customized SAS macros for use in conducting adaptive regression modeling. These macros and code for conducting the analyses discussed in the book are available through the first authors website and online via the books Springer website. Detailed descriptions of how to use these macros and interpret their output appear throughout the book. These methods can be implemented using other programs....3619685Adaptive Regression for Modeling Nonlinear Relationships13601511https://www.gandhi.com.mx/adaptive-regression-for-modeling-nonlinear-relationships-9783319339467/phttps://gandhi.vtexassets.com/arquivos/ids/2475936/42189b43-fa85-4284-8bf8-d25b3669b4f9.jpg?v=638384026890000000InStockMXN99999DIEbook20169783319339467_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_This book presents methods for investigating whether relationships are linear or nonlinear and for adaptively fitting appropriate models when they are nonlinear.
