I have summary results from a large GWAS. The information given in this summary statistics is the following columns:
Chromosome, Position, Markername, Effect_allele, Other_allele, P-value , Zscore.
If i understood it correctly, the Z-score is the standardized effect measure (effect/StdError). Is there a way to create a PRS based on this Zscore instead of based on the original effect-estimates? Or do i have to estimate the beta from the Zscore in any way (by using allele frequency,..)? Has anyone done this before? All advice is appreciated!
