Calculate Z-score, P-value, Chi2 stat from GWAS
2022-04-13
Haky Im
\[Y = \beta \cdot X + \epsilon\] 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.
