WebMar 8, 2016 · in ascertained case control studies or studies with an extreme sample design, REML underestimates chip heritability [32,33]. A long existing alternative to REML for variance component estimation is the minimal norm quadratic unbiased estimation (MINQUE) method, a method of moments (MoM) [34,35]. Because the MINQUE WebFeb 7, 2013 · Since BSLMM is a hybrid of two widely used models, it naturally has a wide range of potential uses. Here we focus on its application to polygenic modeling for genome-wide association studies, specifically two applications of particular interest and importance: PVE estimation (or “chip heritability” estimation) and phenotype prediction.

Webas age, sex and race [8,12]. To identify a trait of high chip h2, we need to solve the inverse problem of (chip) heritability estimation. In other words, we now search for a trait (e.g., a linearly-combined trait) so that its chip heritability is high when estimated using the REML method. Directly solving the inverse problem leads to
