Hello! I'm using ImpG-Summary (Pasaniuc et al, 2014) to perform genotype imputation from summary statistics. However, for each imputed SNP, I only get a z-score, while odds ratio and standard error are missing. The output file has - for each SNP - six columns: name of SNP, position of SNP, Ref allele, Alt allele, Z-score, r2pred; the higher this latter value is, the more confident one is about the result. Can I approximate Odds Ratio, effect size, and standard error somehow? Please let me know. Thanks in advance!
