Given the following informations:
CHR1 Variant 1 chromosome code SNP1 Variant 1 identifier CHR2 Variant 2 chromosome code SNP2 Variant 2 identifier BETA_INT Regression coefficient (QT) STAT Chi-square statistic DF Chi-square degrees of freedom P Chi-square p-value
Is it correct to calculate the Standard error by dividing "BETA_INT" by "STAT"? And if yes, does the Standard error always have to be positive?
Thank you for your help!
