Deep advantage learning for optimal dynamic treatment regime
Statistical Theory and Related Fields, 2018 Recently deep learning has successfully achieved state-of-the-art performance on many difficult tasks. Deep neural networks allow for model flexibility and process features without the need of domain knowledge.

Reference Point Formation Over Time: A Weighting Function Approach [PDF]
Although the concept of reference point dependent preferences has been adopted to almost all fields of behavioral economics, especially marketing and behavioral finance, we still know very little about how decision makers form their reference points ...

Parameter Estimation in Spatial Autoregressive Models with Missing Data and Measurement Errors
AxiomsThis study addresses the problem of parameter estimation in spatial autoregressive models with missing data and measurement errors in covariates. Specifically, a corrected likelihood estimation approach is employed to rectify the bias in the log-maximum ...

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Neurochemical levels measured by brain MR spectroscopy (MRS) have been proposed as endpoints for clinical trials in early‐stage spinocerebellar ataxia (SCA) trials. We tested their trial‐readiness by quantifying neurochemicals in three affected brain regions in early‐stage cohorts of SCA2 and SCA3, examining their reproducibility in ...

A Novel Probability Weighting Method To Fit Gaussian Functions
, 2021 Gaussian functions are commonly used in different fields, many real signals can be modeled into such form. Research aiming to obtain a precise fitting result for these functions is very meaningful. This manuscript intends to introduce a new algorithm used to estimate the full parameters of the Gaussian-shaped function.

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objectives Focal cortical dysplasia (FCD) is the most common etiology of drug‐resistant epilepsy in children. Focal to bilateral tonic–clonic seizures (FBTCS) mark a high risk of drug‐resistant epilepsy and involve thalamocortical circuitry in their generation and propagation.
