Federated generalized additive models for location, scale and shape [PDF]

open access: yesBMC Medical Research Methodology
Background The generalized additive model for location, scale and shape (GAMLSS) is a flexible regression model with a wide range of applications. In particular, it is the standard method to estimate age-specific percentile curves for clinical parameters

Spatial modeling of HIV prevalence in Malawi using generalized additive models [PDF]

open access: yesFrontiers in Epidemiology
IntroductionMalawi has made substantial progress in HIV prevention and treatment, yet HIV prevalence remains unevenly distributed across the country. Sub-national estimates are needed to guide targeted interventions.MethodsWe analyzed individual-level ...

Hierarchical generalized additive models in ecology: an introduction with mgcv [PDF]

open access: yesPeerJ, 2019
In this paper, we discuss an extension to two popular approaches to modeling complex structures in ecological data: the generalized additive model (GAM) and the hierarchical model (HGLM).

Meta-analysis of generalized additive models in neuroimaging studies

open access: yesNeuroImage, 2021
Analyzing data from multiple neuroimaging studies has great potential in terms of increasing statistical power, enabling detection of effects of smaller magnitude than would be possible when analyzing each study separately and also allowing to ...

Building flexible regression models: including the Birnbaum-Saunders distribution in the gamlss package

open access: yesSemina: Ciências Exatas e Tecnológicas, 2021
Generalized additive models for location, scale and shape (GAMLSS) are a very flexible statistical modeling framework, being an important generalization of the well-known generalized linear models and generalized additive models.

Analyzing Temporal Trends of Urban Evaporation Using Generalized Additive Models

open access: yesLand, 2022
This study aimed to gain new insights into urban hydrological balance (in particular, the evaporation from paved surfaces). Hourly evaporation data were obtained simultaneously from two high-resolution weighable lysimeters.

Tariff Analysis in Automobile Insurance: Is It Time to Switch from Generalized Linear Models to Generalized Additive Models?

open access: yesMathematics, 2023
Generalized Linear Models (GLMs) are the standard tool used for pricing in the field of automobile insurance. Generalized Additive Models (GAMs) are more complex and computationally intensive but allow taking into account nonlinear effects without the ...
