Polygenic Risk Score Predicts Prostate Cancer Risk Independent of Type 2 Diabetes
ABSTRACT Aims Type 2 diabetes mellitus (T2DM) has been inversely associated with prostate cancer (PrCa) risk. However, it remains unclear whether a polygenic risk score (PRS) for PrCa can effectively stratify risk among men with T2DM. The primary objective of this study was to assess whether a PrCa PRS predicts PrCa risk independently of T2DM status ...

Regression discontinuity design with covariates [PDF]
In this paper, the regression discontinuity design (RDD) is generalized to account for differences in observed covariates X in a fully nonparametric way. It is shown that the treatment effect can be estimated at the rate for one-dimensional nonparametric

ABSTRACT The present paper provides an overall framework to afford the problem of non‐representativeness and non‐random selectivity arising from online job ads data, using Generalized sample selection models and Eurostat benchmark data. We jointly model the outcome intensity (number of online job ads in observed profiles, whose levels are defined by ...

Productivity Dynamics and Structural Change in the U.S. Manufacturing Sector [PDF]
The paper investigates structural change among the four-digit (SIC) industries of the U.S. manufacturing sector during 1958-96 within a distribution dynamics framework. Focus is on the transition density of the Markov process that characterizes the value

Estimating Correlations Between Clinical Trial Outcomes Using Generalised Estimating Equations
ABSTRACT Accurately estimating the correlations among clinical trial outcomes is crucial for managing the risk of biopharmaceutical investment portfolios. We propose a novel algorithm for estimating correlations in large clinical trial datasets using a generalised estimating equations (GEE) framework.

Interval identification of natural effects in the presence of outcome‐related unmeasured confounding
Abstract With reference to a binary outcome and a binary mediator, we derive identification bounds for natural effects under a reduced set of assumptions. Specifically, no assumptions about confounding are made that involve the outcome; we only assume no unobserved exposure‐mediator confounding as well as a pair of conditions termed Partially Constant ...

Sensitivity analysis for generalized estimating equation with non‐ignorable missing data
Abstract Many incomplete‐data statistical inference procedures are developed under the missing at random (MAR) assumption. However, the MAR assumption has been criticized as being overly strong for real‐data problems, and is unverifiable by using observed data. To handle data that are missing not at random (MNAR), sensitivity analysis has been proposed

Convergence analysis of generalized iteratively reweighted least squares algorithms on convex function spaces [PDF]
The computation of robust regression estimates often relies on minimization of a convex functional on a convex set. In this paper we discuss a general technique for a large class of convex functionals to compute the minimizers iteratively which is ...

Nonparametric Cure Models Through Extreme‐Value Tail Estimation
ABSTRACT In survival analysis, the estimation of the proportion of subjects who will never experience the event of interest, termed the cure rate, has received considerable attention recently. Its estimation can be a particularly difficult task when follow‐up is not sufficient, that is, when the censoring mechanism has a smaller support than the ...
