I want to use a summary statistics of a meta GWAS result. The meta analysis was performed by using META. In the summary statistic table, there are z-score and p-value columns, but no beta or SE columns. But I need beta as my input. Here is header of the summary table
SNP CHR BP Allele1 Allele2 N Zscore P
I know that the conversion between beta and zscore is that:
zscore = beta / SE
How could I calculate beta based on provided info?
