Regression modeling on stratified data with the lasso

, 2016
We consider the estimation of regression models on strata defined using a categorical covariate, in order to identify interactions between this categorical covariate and the other predictors.

A Covariance Equation

The Journal of Geometric Analysis, 2019
Let $ $ be a commutative semigroup with identity $e$ and let $ $ be a compact subset in the pointwise convergence topology of the space $ '$ of all non-zero multiplicative functions on $ .$ Given a continuous function $F: \to \mathbb C$ and a complex regular Borel measure $ $ on $ $ such that $ ( ) \not = 0.$ It is shown that $$ ( ) \int_

Ambivalent covariance models [PDF]

BMC Bioinformatics, 2015
Evolutionary variations let us define a set of similar nucleic acid sequences as a family if these different molecules execute a common function. Capturing their sequence variation by using e. g. position specific scoring matrices significantly improves sensitivity of detection tools.

Real‐World Comparison of High‐Efficacy Versus Non‐High‐Efficacy Therapies in Multiple Sclerosis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective The choice of the first disease modifying treatment (DMT) in multiple sclerosis (MS) is a topic of great interest, and whether high‐efficacy DMTs should be the first choice remains debated. We compared treatment outcomes (no evidence of disease activity [NEDA] and its components) between treatment‐naïve relapsing–remitting MS (RRMS ...

Cognitive Resilience in Apolipoprotein ε4 Carrier Women Predicted by Neuron‐Derived Extracellular Vesicles

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective The Apolipoprotein (APOE) ε4 allele is the strongest genetic risk factor for late‐onset Alzheimer's disease (AD); however, many ε4 carriers remain cognitively intact into old age. Leveraging plasma neuron‐derived extracellular vesicles (NDEVs), we sought to identify biomarkers of cognitive resilience and their interplay with APOE ...

Associations of Stroke With Risk of Epilepsy: Results From the Atherosclerosis Risk in Communities (ARIC) Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To estimate the risk of epilepsy associated with stroke in a community‐based cohort, with consideration of stroke type, number, and severity. Methods Data from 15,100 Atherosclerosis Risk in Communities (ARIC) Study participants without stroke at baseline (1987–1989) were analyzed through 12/31/2022.

Complex Covariance

Acta Polytechnica, 2013
According to some generalized correspondence principle the classical limit of a non-Hermitian quantum theory describing quantum degrees of freedom is expected to be the well known classical mechanics of classical degrees of freedom in the complex phase space, i.e., some phase space spanned by complex-valued space and momentum coordinates.

NOTCH2NLC Repeat Expansions in Parkinsonian Disorders: Clinical and Neuroimaging Characteristics

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Neuronal intranuclear inclusion disease (NIID) is a neurodegenerative disorder caused by NOTCH2NLC GGC repeat expansions, with heterogeneous clinical manifestations, including parkinsonism. Recent studies have identified NOTCH2NLC repeat expansions in patients with Parkinson's disease (PD) and atypical parkinsonism (aPM), suggesting ...

Entropy balancing is doubly robust

, 2016
Covariate balance is a conventional key diagnostic for methods used estimating causal effects from observational studies. Recently, there is an emerging interest in directly incorporating covariate balance in the estimation.
