Going Off the Grid: Iterative Model Selection for Biclustered Matrix Completion
JOURNAL OF COMPUTATIONAL AND GRAPHICAL STATISTICS, 28(1), 36–47.
author keywords: Convex optimization; Degrees of freedom; Hutchinson estimator; Information criterion; Penalization; Sparse linear systems
TL;DR:
This work presents a novel iterative procedure for directly minimizing an information criterion to select an appropriate amount of row and column smoothing, namely, to perform model selection.

MM ALGORITHMS FOR VARIANCE COMPONENT ESTIMATION AND SELECTION IN LOGISTIC LINEAR MIXED MODEL
STATISTICA SINICA, 29(3), 1585–1605.
author keywords: Generalized linear mixed model (GLMM); Laplace approximation; MM algorithm; variance components selection
TL;DR:
Two efficient and stable minorization-maximization algorithms for estimating variance components based on a Laplace approximation of the logistic model and a simple iterative soft-thresholding algorithm for variance component selection using the maximum penalized approximated likelihood.

MM Algorithms for Variance Components Models
JOURNAL OF COMPUTATIONAL AND GRAPHICAL STATISTICS, 28(2), 350–361.
author keywords: Global convergence; Linear mixed model (LMM); Matrix convexity; Maximum a posteriori (MAP) estimation; Minorization-maximization (MM); Multivariate response; Penalized estimation; Variance components model
TL;DR:
The global convergence of the MM algorithm to a Karush–Kuhn–Tucker point is established and it is demonstrated that it converges faster than the classical EM algorithm when the number of variance components is greater than two and all covariance matrices are positive definite.

Heal rate of metatarsal fractures: A propensity-matching study of patients treated with low-intensity pulsed ultrasound (LIPUS) vs. surgical and other treatments
INJURY-INTERNATIONAL JOURNAL OF THE CARE OF THE INJURED, 47(11), 2584–2590.
author keywords: Jones fracture; Open fracture; Tobacco smoking; Obesity
MeSH headings : Adult; Female; Fracture Fixation, Internal; Fracture Healing / physiology; Fractures, Bone / diagnostic imaging; Fractures, Bone / pathology; Fractures, Bone / therapy; Humans; Male; Metatarsal Bones / diagnostic imaging; Metatarsal Bones / injuries; Metatarsal Bones / pathology; Propensity Score; Retrospective Studies; Treatment Outcome; Ultrasonic Therapy
TL;DR:
It is proposed that metatarsal fractures treated conservatively with non-invasive low-intensity pulsed ultrasound (LIPUS) obtain heal rates comparable to current surgical techniques, suggesting that these variables were perceived as nonunion risk factors by prescribing physicians.
