3 Jun 2024: Seeking to overcome these limitations, we propose a new approach to sensitivity analysis based on the inverse probability weighting estimator.

3 Jun 2024: Then,. Var(β̃) = σ2(XTX)1 σ2DDT = Var(β̂) σ2DDT. In particular, β̂ being BLUE means that given a new observation x Rp, we can estimatethe regression function at x optimally ... 9. Prediction intervals. Let x Rp be a new observation. We can

3 Jun 2024: We derive a new class of linear IV estimates that are robust to sample heterogeneity.

3 Jun 2024: May 2020Abstract. We greatly improve the applicability of MR-RAPS. The new GRAPPLE framework can handle multiple exposures and overlapping exposure and outcomes GWAS, and is able to detect multiple pleiotropic

3 Jun 2024: I will describe a new statistical framework called Robust Adjusted Profile Score (MR-RAPS) which can provide efficient and robust inference in such problems, by exploiting weak genetic instruments and limiting

3 Jun 2024: Qingyuan Zhao, Dylan Small. May 2018Abstract. This research letter proposes a new diagnostic plot for IV analysis, so large bias ratios (compared to OLS estimator) are not over-interpreted when the

3 Jun 2024: A new Bayesian full-information method for life-course Mendelian randomization. By combining causal graphs and randomization inference, a formal justification for Mendelian randomization is given in the context of ... The idea of MR can be traced back to

3 Jun 2024: Qingyuan Zhao, Dylan Small, Paul Rosenbaum. March 2017Abstract. This paper proposes a new method called ‘cross-screening’ to increase the power of sensitivity analysis when multiple causal hypotheses need to be

3 Jun 2024: This paper proposes a new method called 'cross-screening' to increase the power of sensitivity analysis when multiple causal hypotheses need to be tested simultaneously.

3 Jun 2024: A new Bayesian full-information method for life-course Mendelian randomization. By combining causal graphs and randomization inference, a formal justification for Mendelian randomization is given in the context of ... We greatly improve the applicability

3 Jun 2024: Search. Sensitivity Analysis. A new approach to sensitivity analysis in linear SEMs using stochastic optimization and the $R2$-calculus.

3 Jun 2024: I am interested in improving the general quality and appraisal of statistical research, including new methodology and a better understanding of causal inference, novel study designs, sensitivity analysis, multiple testing, and

3 Jun 2024: A new Bayesian full-information method for life-course Mendelian randomization. Zixuan Wu, Ethan Lewis, Qingyuan Zhao, Jingshu Wang. ... The new GRAPPLE framework can handle multiple exposures and overlapping exposure and …. Jingshu Wang, Qingyuan Zhao,

3 Jun 2024: The increasing availability and scale of Genome Wide Association Studies (GWAS) bring new horizons for understanding biological mechanisms.

3 Jun 2024: To add this new publication to my webpage, I can execute the following command. ... So my homepage only contains two widgets. Additionally, I created a custom widget page called news to make announcements and display new content.

3 Jun 2024: We propose using an estimand new for this context—the causal risk ratio, which has more transparent interpretation and requires weaker identification assumptions.

3 Jun 2024: Treatment Ai A = {0, 1}. Example: a new drug. –

3 Jun 2024: Scientific research is usually an iterative process. The cycle: conjecture-design-experiment-analysis leads to a new cycle of conjecture-design-experiment-analysis and so on. ... statisticians (including me) are trained to develop new techniques and most
