Spatial regression modeling via the R2D2 framework

Yanchenko, E., Bondell, H. D., & Reich, B. J. (2023, October 27). *ENVIRONMETRICS*, Vol. 10.

author keywords: Bayesian inference; coefficient-of-determination; Gaussian process; generalized beta prime distribution; penalized regression

TL;DR:
The effect of marine policies on biodiversity is estimated and it is concluded that no‐take restrictions lead to a slight increase in biodiversity and that the majority of the variance in the linear predictor comes from the spatial effect.

Simultaneous Factor Selection and Collapsing Levels in ANOVA

Bondell, H. D., & Reich, B. J. (2009, March). *BIOMETRICS*, Vol. 65, pp. 169–177.

author keywords: ANOVA; Grouping; Multiple comparisons; Oracle property; Shrinkage; Variable selection

MeSH headings : Analysis of Variance; Biometry / methods; Computer Simulation; Data Interpretation, Statistical; Models, Theoretical; Regression Analysis

TL;DR:
A novel constrained regression approach to simultaneously accomplish both goals via shrinkage within a single automated procedure is proposed, which has the ability to collapse levels within a factor by setting their effects to be equal, while also achieving factor selection by zeroing out entire factors.

Variable Selection in Bayesian Smoothing Spline ANOVA Models: Application to Deterministic Computer Codes

*TECHNOMETRICS*, *51*(2), 110–120.

author keywords: Bayesian hierarchical modeling; Markov chain Monte Carlo; Nonparametric regression; Smoothing splines ANOVA; Variable selection

TL;DR:
This work proposes a Bayesian nonparametric regression model for curve fitting and variable selection, uses the smoothing splines ANOVA framework, and uses stochastic search variable selection through Markov chain Monte Carlo sampling to search for models that fit the data well.

Simultaneous regression shrinkage, variable selection, and supervised clustering of predictors with OSCAR

*BIOMETRICS*, *64*(1), 115–123.

author keywords: correlation; penalization; predictive group; regression; shrinkage; supervised clustering; variable selection

MeSH headings : Algorithms; Artificial Intelligence; Biometry / methods; Cluster Analysis; Computer Simulation; Data Interpretation, Statistical; Epidemiologic Methods; Models, Biological; Models, Statistical; Regression Analysis

TL;DR:
A new method called the OSCAR (octagonal shrinkage and clustering algorithm for regression) is proposed to simultaneously select variables while grouping them into predictive clusters, in addition to improving prediction accuracy and interpretation.

Statistical inference based on pooled data: A moment-based estimating equation approach

*JOURNAL OF APPLIED STATISTICS*, *34*(2), 129–140.

author keywords: pooling biospecimens; set-based observations; moments; Box-Cox transformation; goodness-of-fit; lognormal distribution

TL;DR:
A moment-based estimating equation approach is proposed to deal with situations where likelihood functions based on pooled data are difficult to work with and is demonstrated on the family of distributions generated by the Box–Cox transformation model.
