Conditional Model Selection in Mixed-effects Models with lme4

In addition to many possibilities to extend these simple random e ect models, linear mixed models can also be utilized to t semi-parametric regression models (see, e.g.,Ruppert, Wand, and Carroll2003). For univariate smoothing, consider the model E(y i) = f(x i); (5) for i= 1;:::;n, where f() is a deterministic function of the covariate x i, which shall be approximated using splines. For ...

Parametric versus Semi and Nonparametric Regression Models

2.2 Nonparametric models The parametric and nonparametric models di er in that the model form is not speci ed a priori but is instead determined from data set. The term nonparametric does not mean that such models are completely lack parameters, but that the number of the parameters are exible and not xed periori. In parametric models, the vector of parameter, , is a vector in nite p ...

Generalized Additive Models for Location Scale and Shape ...

Generalized additive models for location, scale and shape (GAMLSS) are semi-parametric regression type models. They are parametric, in that they require a parametric distribu-tion assumption for the response variable, and semi" in the sense that the modelling of the parameters of the distribution, as functions of explanatory variables, may involve using non-parametric smoothing functions ...

Models for longitudinal and time-to-event data are proposed in the context of joint modeling. Three alternative regression models for the longitudinal data are presented with time evolution based on Generalized Hierarchical Dynamic Linear Model. These regression models are standard, quantile and Markov switching regression. For the survival baseline hazard function some parametric and semi ...

Chapter IV SEMI-PARAMETRIC REGRESSION MODEL

Semi-parametric regression models contain components of parametric and nonparametric regression models and in some sense combine the advantages and disadvantages of parametric and nonparametric regression models. In case of an optimal combination of the two approaches, the semi-parametric regression model has the efficiency (low variance) of parametric models and the flexibility (small bias ...

Semiparametric Regression with R - Matt Wand

Chapter 1 Introduction 1.1 Semiparametric Regression Regression is used to understand the relationships between predictor variables and response variables and for predicting the latter using the former. In parametric regression, the effect of each predictor has a simple form, for example, is a linear or exponential function, so that its overall shape is dictated by the model, not the data.

Robust Semiparametric Regression Estimation Using Targeted ...

Parametric methods used to estimate these e ects are prone to bias. This bias is often the result of incorrect model spec-i cation and improper inference for the parameter of interest. Alternative machine learning techniques, such as Random Forest, often result in abstract measures of im-portance whose inference depends on a computationally intensive bootstrap analysis. In this thesis, robust ...

Variable selection in semiparametric regression modeling

Ruppert, Wand and Carroll [21] and Yatchew [26] present diverse semi-parametric regression models along with their inference procedures and applications. The goal of this paper is to develop eﬀective model selec-tion procedures for a class of semiparametric regression models. Let Y be a response variable and {U,X,Z} its associated covariates. Further, let µ(u,x,z) = E(Y|U = u,X = x,Z = z ...

than for the parametric approach; its stochastic properties derive from its definition in terms of the functional g(.) rather than a prior behavioral assumption. Estimation of the function g(.) is straightforward once a suitable estimator gYIX of the conditional distribution of y given x is obtained; if the functional T(.) in (1.3) is well-behaved (i.e. continuous over the space of possible I ...
