A Computationally Efficient Projection-Based Approach for Spatial Generalized Linear Mixed Models [PDF]

open access: yesJournal of Computational And Graphical Statistics, 2016
Inference for spatial generalized linear mixed models (SGLMMs) for high-dimensional non-Gaussian spatial data is computationally intensive. The computational challenge is due to the high-dimensional random effects and because Markov chain Monte Carlo ...

Bayesian variable selection in linear quantile mixed models for longitudinal data with application to macular degeneration.

open access: yesPLoS ONE, 2020
This paper presents a Bayesian analysis of linear mixed models for quantile regression based on a Cholesky decomposition for the covariance matrix of random effects.

Additive quantile mixed effects modelling with application to longitudinal CD4 count data

open access: yesScientific Reports, 2021
Quantile regression offers an invaluable tool to discern effects that would be missed by other conventional regression models, which are solely based on modeling conditional mean.

Combining the Box-Cox power and generalised log transformations to accommodate nonpositive responses in linear and mixed-effects linear models

open access: yesSouth African Statistical Journal, 2022
Transformation of a response variable can greatly expand the class of problems for which the linear regression model or linear mixed-model is appropriate.

The development of a simple basal area increment model [PDF]

open access: yes, 2011
In most cases forest practice in Austria use yield tables to predict the growth of their forests. Common yield tables show the increment of pure even-aged stands which are treated in a way the table developer recommends.

Mixed Lasso estimator for stochastic restricted regression models

open access: yesJournal of Applied Statistics, 2021
Parameters of a linear regression model can be estimated with the help of traditional methods like generalized least squares and mixed estimator. However, recent developments increased the importance of big data sets, which have much more predictors than

Optimal Antibody Purification Strategies Using Data-Driven Models

open access: yesEngineering, 2019
This work addresses the multiscale optimization of the purification processes of antibody fragments. Chromatography decisions in the manufacturing processes are optimized, including the number of chromatography columns and their sizes, the number of ...

Bayesian multimodel inference for geostatistical regression models. [PDF]

open access: yesPLoS ONE, 2011
The problem of simultaneous covariate selection and parameter inference for spatial regression models is considered. Previous research has shown that failure to take spatial correlation into account can influence the outcome of standard model selection ...

Statistical primer: an introduction to the application of linear mixed-effects models in cardiothoracic surgery outcomes research—a case study using homograft pulmonary valve replacement data

open access: yesEuropean Journal of Cardio-Thoracic Surgery, 2022
Summary OBJECTIVES The emergence of big cardio-thoracic surgery datasets that include not only short-term and long-term discrete outcomes but also repeated measurements over time offers the opportunity to apply more advanced modelling of outcomes.
