\[Y = \beta \cdot X + \epsilon\] GWAS summary statistics will contain an estimate of the regression coefficient \(\hat\beta\) and its standard error \(\text{se}(\hat\beta)\) for each SNP in the GWAS. We distinguish the true \(\beta\) from the estimated value \(\hat\beta\) using a hat. […] \[ … Read more →
