Pediatric Blood &Cancer, EarlyView.ABSTRACT Treatment‐associated hepatotoxicity (TAH) is a common complication of pediatric acute lymphoblastic leukemia (ALL) treatment, but genetic risk factors remain poorly understood. We evaluated the SOD2 rs4880 variant in 544 children with ALL at Texas Children's Hospital. After adjusting for demographic and clinical covariates, the rs4880 C allele

The Annals of Statistics, 1987 Let \(y_ t=x'_ t\beta +u_ t\), \(t\in Z^ 1\), where the disturbances \(u_ t\) follow a second-order stationary process with E \(u_ t=0\). The spectral density f(\(\lambda)\) of a process \(u_ t\) is unknown but belongs to a neighborhood of some special spectral density \(f_ 0(\lambda)\).

The shooting S-estimator for robust regression [PDF]
, 2015 To perform multiple regression, the least squares estimator is commonly used. However, this estimator is not robust to outliers. Therefore, robust methods such as S-estimation have been proposed.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Osteosarcoma (OS) and Ewing sarcoma (EWS) are the most common primary bone cancers in children, but acute thrombosis is poorly characterized in this population. Our study evaluated the rates of venous thromboembolism (VTE) and associated risk factors in pediatric patients with bone sarcomas treated over a 10‐year period encompassing

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background This study investigated how neighborhood‐level social determinants of health (SDOH), including redlining and neurological risk, interact to influence cognitive outcomes in children treated for brain tumors (CTBT). Methods A retrospective chart review of 161 CTBT aged 5–17 was conducted.

Robust Regression via Hard Thresholding [PDF]
, 2015 We study the problem of Robust Least Squares Regression (RLSR) where several response variables can be adversarially corrupted. More specifically, for a data matrix X \in R^{p x n} and an underlying model w*, the response vector is generated as y = X'w* +

AxiomsIn modern survey sampling, particularly when using stratified random sampling (StRS), the existence of outliers and model mis-specifications is a daunting challenge to the conventional parametric and nonparametric methods of estimating parameters.

The impact of politics on fiscal behavior: the case of Brazil
Economia Aplicada, 2006 This paper examines the proposition that a government which faces an election or depends on general popular support to govern effectively will find it difficult to resist increasing expenditures or to raise taxes.
