Czech Journal of Animal Science, 2018 Exploration of genetic variance has mostly been limited to additive effects estimated using pedigree data and non-additive effects have been ignored. This study aimed to evaluate the performance of single nucleotide polymorphisms (SNPs) marker models in ...

Additive and Multiplicative Models and Interactions
The Annals of Statistics, 1983 A unified treatment is given of the classical additive models for complete factorial experiments and of multiplicative models and Lancaster-additive models for multi-dimensional contingency tables. The models are characterized by properties of being simplest subject to having a prescribed set of marginals. It is shown that, by using averaging operators

Modeling the short-term effect of traffic on air pollution in Torino with generalized additive models [PDF]
Vehicular traffic typically plays an important role in atmospheric pollution. This is especially true in urban areas, where high pollutant concentrations are often observed. In this paper, we consider hourly measures of concentrations of nitrogen oxides (

Efficient Estimation of an Additive Quantile Regression Model [PDF]
In this paper two kernel-based nonparametric estimators are proposed for estimating the components of an additive quantile regression model. The first estimator is a computationally convenient approach which can be viewed as a viable alternative to the ...

Geo-additive models of childhood undernutrition in three sub-Saharan African countries [PDF]
, 2009 We investigate the geographical and socioeconomic determinants of childhood undernutrition in Malawi, Tanzania and Zambia, three neighbouring countries in southern Africa, using the 1992 Demographic and Health Surveys.

Probabilistic Hourly Load Forecasting Using Additive Quantile Regression Models
Energies, 2018 Short-term hourly load forecasting in South Africa using additive quantile regression (AQR) models is discussed in this study. The modelling approach allows for easy interpretability and accounting for residual autocorrelation in the joint modelling of ...

Variable Selection in Additive Models by Nonnegative Garrote [PDF]
We adapt Breiman's (1995) nonnegative garrote method to perform variable selection in nonparametric additive models. The technique avoids methods of testing for which no reliable distributional theory is available.

additive: Bindings for Additive TidyModels [PDF]
Fit Generalized Additive Models (GAM) using 'mgcv' with 'parsnip'/'tidymodels' via 'additive' . 'tidymodels' is a collection of packages for machine learning; see Kuhn and Wickham (2020) ). The technical details of 'mgcv' are described in Wood (2017) .To

Generalized additive models for large data sets
, 2015 We consider an application in electricity grid load prediction, where generalized additive models are appropriate, but where the data set's size can make their use practically intractable with existing methods.
